There is a particular kind of hush that falls over a crowd in the seconds before a great Christmas tree lights up. Thousands of people count down together, the switch is thrown, and a dark plaza suddenly glows. In 2026, that moment plays out in city squares across the United States — and in London — from mid-November to the first week of December, and almost every ceremony is free.

This guide covers the Christmas tree lighting ceremonies 2026 worth planning around: Rockefeller Center in New York, the National Christmas Tree in Washington, DC, Chicago’s Millennium Park lighting, Boston Common, San Francisco’s Union Square, The Grove in Los Angeles, and the Trafalgar Square tree in London. Every date below comes from the official city, venue, or organizer page for that ceremony. Where an organizer had not published a 2026 date when we checked, we say so plainly and give you the traditional timing instead of a guess. For the wider season, our roundup of the best Christmas events in the USA for 2026 covers markets, parades, and light displays nationwide.

The 2026 Ceremonies at a Glance

Rockefeller Center, New York City — Wednesday, December 2, 2026

The most famous tree lighting on earth closes out the season’s big nights. The 2026 Rockefeller Center Christmas Tree Lighting Ceremony takes place on Wednesday, December 2, 2026, from 7 to 10 p.m. ET at Rockefeller Plaza, between West 49th and 50th Streets in Midtown Manhattan.

The tree. This year’s tree is a 76-foot Norway spruce, roughly 75 years old, donated from West Edmeston, New York. It measures about 50 feet across and weighs around 11 tons. It arrives at Rockefeller Plaza on Saturday, November 7 — the center hosts a free, family-friendly “Meet the Tree Day” from 10 a.m. to 1 p.m. as it is installed — and once decorated it will carry more than 50,000 multicolored LED lights strung along roughly five miles of wire. On top sits the Swarovski star designed by architect Daniel Libeskind: about 900 pounds, with 70 spikes covered in three million crystals.

How to watch. Here is the part many visitors get wrong: the lighting ceremony itself is not open to the public. The plaza is closed for the televised production, and surrounding streets are shut and heavily policed. The intended way to watch is NBC’s annual Christmas in Rockefeller Center special, during which the tree is lit live; NBC confirms the broadcast’s airtime and streaming details closer to December 2, so check NBC’s schedule that week. In person, the smart move is to come from December 3 onward, when the lit tree is on public display daily through mid-January 2027 — combine it with the skating rink at its base and the Fifth Avenue windows using our Christmas in New York City guide.

Distinctive detail. Rockefeller Center’s head gardener, Erik Pauzé, has scouted and selected the annual tree for more than three decades. And when the season ends, the tree is milled into lumber and donated to Habitat for Humanity for home building. The formal ceremony dates to 1933.

National Christmas Tree, Washington, DC — Thursday, December 3, 2026

One day after Rockefeller, the nation’s own tree lights up on the Ellipse at President’s Park, just south of the White House fence. The 2026 National Christmas Tree Lighting takes place on Thursday, December 3, 2026, hosted by the National Park Service and the National Park Foundation, with live musical performances and the President traditionally taking part.

How to watch in person. Attendance at the ceremony is by ticket only — but the tickets are free, distributed through a public lottery on Recreation.gov. For 2026, the lottery opened at 10 a.m. ET on Wednesday, October 28 and closes at 3 p.m. ET on Wednesday, November 4; winners are notified on Thursday, November 12, and each winner can receive up to five tickets. If you are reading this before November 4, entering costs nothing and takes minutes.

How to watch from home, and visiting later. The ceremony gets a nationwide television premiere on Saturday, December 5, 2026 (check thenationaltree.org for the broadcast outlet). Miss the big night entirely and you lose very little: the tree grounds open to the public from December 7, 2026 through January 1, 2027, the lights switch on near sunset each evening, and the surrounding Pathway of Peace displays dozens of smaller trees representing the states and territories, decorated with ornaments made by students.

Distinctive detail. The tradition is older than Rockefeller’s: the first National Christmas Tree was lit in 1923, making the 2026 ceremony part of a run that has lasted more than a century.

Chicago, Millennium Park — Friday, November 20, 2026

Chicago lights the earliest tree on this list — and builds a whole evening around it. The 113th Annual City of Chicago Christmas Tree Lighting is set for Friday, November 20, 2026, at Millennium Park, near Michigan Avenue and Washington Street. Per the city’s announcement, public festivities build from about 4 p.m., the ceremony begins at 6 p.m. CT, and the tree itself is lit at around 6:30 p.m., followed by fireworks. Large viewing screens are placed around the park, the stage sits on Washington Street beside the Chicago Cultural Center, and ABC7 is the broadcast partner for those watching from home. Admission is free and no tickets are needed; the tree then stays on display through January 10, 2027.

Make a night of it. November 20 is also opening day at Christkindlmarket, the German-style Christmas market at Daley Plaza, a short walk west along Washington Street — so you can browse the stalls in the afternoon, walk over for the 6 p.m. ceremony, and be back among the glühwein stands by seven. Our Christkindlmarket Chicago 2026 guide has the market’s dates, hours, and food highlights. The next evening, Saturday, November 21, the Magnificent Mile Lights Festival parade rolls down Michigan Avenue.

Distinctive detail. At 113 editions, Chicago’s is one of the longest-running municipal tree lightings in the country — and it still ends the old-fashioned way, with fireworks over the park.

Boston Common — Thursday, December 3, 2026

Boston’s ceremony carries the best story of the season. The 85th annual Boston Common Tree Lighting runs Thursday, December 3, 2026, from 6 to 8 p.m., beside the Visitor Information Center at 139 Tremont Street, hosted by Mayor Michelle Wu and the Boston Parks and Recreation Department together with the Province of Nova Scotia. WCVB Channel 5 broadcasts the celebration live from 7 p.m. for anyone watching from home.

The tree. Nova Scotia has sent Boston a Christmas tree every year since 1971 — 2026 marks the 55th gift — as thanks for the relief Boston sent after the Halifax Explosion of December 6, 1917, when a munitions ship blew up in Halifax Harbor. This year’s tree is a 45-foot white spruce donated by Ronald and Claire Feener of Lunenburg County, Nova Scotia; it is welcomed on the Common at about 11 a.m. on Tuesday, November 17. On the night, the tree’s lights come on shortly before 8 p.m. alongside lights on more than 80 other trees across the Common and the Public Garden, and at about 8:15 p.m. the celebration moves a few blocks west for the lighting of Commonwealth Avenue Mall.

Distinctive detail. No other major American tree lighting is an act of gratitude between two countries — Boston’s tree is quite literally a thank-you note, renewed every year for over five decades.

Trafalgar Square, London — Thursday, December 3, 2026 (Expected)

London’s great tree is also a thank-you gift. The City of Oslo has sent a Norwegian spruce to Trafalgar Square every year since 1947, in gratitude for Britain’s support of Norway during the Second World War. The tree — typically more than 20 meters tall and 50 to 60 years old — is dressed in traditional Norwegian style, with vertical strings of lights rather than baubles, and carol singers perform beneath it on December evenings.

Date status, honestly. London’s City Hall had not published a formal 2026 ceremony announcement when we checked. The lighting traditionally takes place on the first Thursday of December, which falls on Thursday, December 3, 2026, with the ceremony running from about 5 p.m. — treat that date as expected rather than confirmed, and check london.gov.uk or visitlondon.com before traveling specifically for it. The ceremony is free and unticketed; Charing Cross is the nearest Tube station. There is no national TV broadcast of the switch-on itself, so this is an in-person-only event — arrive early, as the square fills.

Distinctive detail. The tree is selected from forests outside Oslo years in advance and is sometimes nicknamed the “queen of the forest” before it is felled and shipped to London.

San Francisco, Union Square — Late November (Date TBA)

San Francisco’s official season opener is Macy’s Great Tree Lighting in Union Square, in the heart of the downtown shopping district. Macy’s and the Union Square Alliance had not posted a confirmed 2026 ceremony date when we checked. Traditionally, the ceremony falls on the Friday after Thanksgiving — which would be Friday, November 27, 2026 — starting in the early evening, with the tree lit at around 6:50 p.m. in recent editions. Confirm the date on the Union Square Alliance’s site before making plans.

The tree itself is a reusable artificial tree — the city’s SFMTA has described it in recent seasons as carrying some 43,000 LED lights and roughly 700 ornaments — and it stays lit nightly through the New Year. The Union Square ice rink operates right beside it, and the Winter Walk food-truck plaza takes over two blocks of Stockton Street for the season. The whole event is free and unticketed; the BART and Muni station at Powell Street is a two-minute walk away.

Los Angeles, The Grove — Mid-November (Date TBA)

Los Angeles does its tree lighting earliest and warmest. The annual “Christmas at The Grove” Tree Lighting Celebration lights a 100-foot white fir — trucked in from the Mount Shasta region and installed at The Park inside The Grove shopping district, next to the Original Farmers Market — with a televised evening show of live performances, Santa’s arrival, and a fireworks and drone finale in recent editions.

Date status, honestly. The Grove had not announced its 2026 celebration date when we checked. In recent years the show has run on a mid-November evening, starting at 7 p.m. — expect a similar slot in 2026 and confirm at thegrovela.com. Even if you miss the show, the tree is lit nightly all season, and in recent seasons The Grove has staged nightly snowfall shows at 7 and 8 p.m. over the plaza through Christmas. Entry to the grounds is free; the celebration night draws very large crowds, so arrive well ahead of showtime.

Tips for Attending a Tree Lighting in 2026

• Arrive earlier than feels necessary. For the free public ceremonies — Chicago, Boston, London, San Francisco — the good sightlines go one to two hours before the switch-on. Chicago’s screens help, but Boston Common and Trafalgar Square reward early arrivals.
• Expect security screening and street closures. Big-city ceremonies close surrounding blocks and may include bag checks. Travel light, and know your exit route before the countdown starts.
• Dress for standing still. You will be outdoors, mostly stationary, for one to three hours — in Chicago, Boston, and DC that can mean below-freezing wind. In London, bring rain gear; in Los Angeles, a light jacket is genuinely enough.
• Use transit. Every ceremony on this list sits on top of a subway, T, CTA, BART/Muni, or Tube station, and driving anywhere near one on the night is a mistake.
• Have a Plan B night. Every tree here stays lit for weeks — Rockefeller and Chicago into mid-January, the National Tree grounds through January 1. A quiet Tuesday evening visit beats a rained-out ceremony night, and the photos are better.
• Re-check the official page the week of. Times shift, TBA dates land, and broadcasters confirm streaming details late. The organizer’s own page — not a roundup like this one — is the final word.

Frequently Asked Questions

When is the Rockefeller Center tree lighting in 2026? Wednesday, December 2, 2026, from 7 to 10 p.m. ET. The ceremony is a televised production and is not open to the public in the plaza; watch NBC’s Christmas in Rockefeller Center special, then visit the lit tree in person any day from December 3 through mid-January 2027.

How do I get tickets for the National Christmas Tree lighting? Tickets are free and distributed by lottery on Recreation.gov. For the December 3, 2026 ceremony, the lottery opened October 28 and closes at 3 p.m. ET on November 4, 2026, with winners notified on November 12 and up to five tickets per winner. If you miss out, the tree grounds open free to everyone from December 7, 2026 to January 1, 2027.

Which 2026 tree lighting ceremonies are free to attend in person? Chicago, Boston, London, San Francisco, and Los Angeles are all free, unticketed public gatherings — just show up early. The two exceptions are Rockefeller Center, where the ceremony itself is closed to the public, and the National Christmas Tree, which requires a (free) lottery ticket for the ceremony night only.

What if I miss the lighting night? Almost nothing is lost. The trees stay up and lit every evening for four to seven weeks — through January 1 in Washington, January 10 in Chicago, and mid-January in New York. The ceremony is a party; the tree is the attraction, and it waits for you.

When will the still-unannounced 2026 dates be confirmed? London, San Francisco, and Los Angeles traditionally confirm in the fall, and all three were still pending when we checked in late October 2026. The expected dates — Thursday, December 3 for Trafalgar Square, Friday, November 27 for Union Square, and a mid-November evening for The Grove — follow each event’s long-standing pattern, but check the official venue pages before booking travel around them.
