Halloween in Las Vegas 2026 (Saturday, October 31)

October 31, 2026 falls on a Saturday, the first Saturday Halloween since 2020, and Las Vegas treats that as a two-night holiday: Friday is the warm-up, Saturday carries the headline parties, and the clocks fall back at 2 a.m. on Sunday, November 1, so the last night runs an extra hour. The casino mask rules haven't changed, the weather is close to perfect, and the confirmed 2026 list is short but real.

What's confirmed for Halloween 2026, and what isn't yet

Locked in as of September 2, 2026:

• Sin City Halloween Ball, Saturday, October 31, The Theater at Virgin Hotels Las Vegas, doors 8:30 p.m., 9 p.m. to 3 a.m., 21+. It's the 30th edition; the 2026 theme is "Lost Vegas Wasteland".
• Martin Garrix at OMNIA inside Caesars Palace on Halloween night, 10:30 p.m., 21+, with Justin Mylo.
• The Chainsmokers at Encore Beach Club at Night on October 31, per Wynn's calendar; XS itself is closed for renovation until November 5.
• ScAREA15: Strange Circus, AREA15's own Halloween party, doors 8 p.m., 18+ (21 to drink), with Valentino Khan and Henry Fong on the bill.
• Universal Horror Unleashed at AREA15 runs year-round; its HamiKuma takeover covers September and October, and Krampus & Kin follows in November.
• HallOVeen at the Magical Forest, October 2–4 and 9–31, and Haunted Harvest at Springs Preserve, October 22–25, $14: the two family events with 2026 dates posted.
• Concerts: Mary J. Blige at Dolby Live and Earth, Wind & Fire at The Venetian Theatre both play October 30 and 31.
• Zombie Burlesque plays its usual 8 p.m. show at the V Theater on both nights, and The Wizard of Oz at Sphere has screenings on October 30 and 31.

Still unannounced: Fremont Street's 2026 program, Circa's Halloween party, any Sphere costume screenings, the seasonal pop-up haunts, Downtown Summerlin's parade dates, Freakling Bros, and the other megaclubs' Halloween-weekend lineups. Those typically post in September and October.

Downtown: Fremont Street on Halloween night

Picture five blocks of canopy, a light show at the top of every hour from 6 p.m. to 2 a.m., and several thousand people in costume holding plastic cups. That's downtown on October 31, and it costs nothing. In 2025 the Fremont Street Experience ran "Costumes Under the Canopy": contest registration from 6 to 8:30 p.m. at the check-in table behind the 3rd Street Stage next to The D, judging from 9 p.m. on that stage, up to $5,000 in cash across the top three places, and no ticket for any of it. The contest was 21+ with ID; the crowd is all ages. Real or replica weapons were banned, along with nudity and offensive imagery, and the free live stages ran as they do every night.

Fremont Street Experience hadn't posted a 2026 version as of September 2, and Circa's events calendar showed nothing for the weekend either, so check both in October. The pattern has held for years, and a Saturday date is exactly the kind of night the district builds a program around.

Drinks under the canopy must be in plastic or paper cups from a bar or casino inside the district; glass, cans and store-bought bottles get confiscated. On a Saturday Halloween the mall goes shoulder to shoulder well before the 9 p.m. judging, so if you're bringing kids, catch the 6 and 7 p.m. canopy shows and be gone by 8.

Club parties and the Sin City Halloween Ball

Thirty years in, the Sin City Halloween Ball is the one Halloween party in town with a real dress code: costume, formal wear or fantasy wear is mandatory, and the door turns away street clothes with no refund. The 2026 edition is Saturday, October 31 at The Theater at Virgin Hotels Las Vegas, doors 8:30 p.m., 9 p.m. to 3 a.m., 21+, with stage performances every 20 minutes and DJs between them. Early-bird general admission was $121.82 all-in on the official site as of September 2, non-refundable. VIP costs more, with fees on top, and adds a separate entrance, an open bar pouring call liquor, VIP-only seating and restrooms, and the only in-and-out privileges in the building. Banned: toy or real guns, realistic weapons, metal spikes, pasties, liquid latex. Full-face masks are allowed inside the theater but not on the casino floor or in the hotel's public areas, so the organizers tell masked guests to enter through the parking garage off Paradise Road. They also warn that parking is limited and recommend a rideshare or taxi.

On the Strip, the megaclubs book Halloween Saturday like a headliner night. Confirmed so far: Martin Garrix with Justin Mylo at OMNIA at 10:30 p.m. on October 31, 21+, by table or general admission. Wynn's calendar lists The Chainsmokers at Encore Beach Club at Night the same evening, because XS has been dark since August 1 for a full renovation and doesn't reopen until November 5. Marquee and TAO hadn't announced Halloween-weekend headliners on their venue pages as of September 2; expect those lineups to post through the fall. OMNIA's regular cover runs $20–75 for women and $30–100 for men and spikes on holiday weekends, with no real free guest list, so buy an advance ticket rather than gambling on the door. Friday tickets usually run cheaper than Saturday's.

Off the Strip, AREA15 has posted ScAREA15: Strange Circus for October 31: doors 8 p.m., aerialists and circus performers alongside an EDM bill led by Valentino Khan and Henry Fong, spread across three of its spaces, 18 and over, 21 to drink. Prices weren't listed when we checked.

Costume rules inside casinos, clubs and venues

Vampire makeup passes; a Michael Myers mask does not. Every casino operator applies the same year-round security logic on Halloween: staff must be able to match your face to your ID and to the cameras. Virgin Hotels spells it out for the night of the Ball: masks, and makeup with facial prosthetics, are not allowed on the casino floor or in the hotel's public areas, even for ticket holders. Springs Preserve bans full-face masks for adults 18 and over at its family event, and Universal Horror Unleashed refuses face masks and anything that obstructs the face. Fake weapons of any kind, replica firearms and swords included, were banned at Fremont Street's 2025 contest and are banned at the Ball, and you should assume casino security works from the same list.

Nightclubs add their own layer: the regular dress code still applies underneath the costume, so Tao Group's rooms bar sports attire, athleisure and swimwear even on October 31, and the mask and weapons rules follow you to the club door, where borderline calls go the bouncer's way. The workable approach is a costume that's recognizable from the neck up, with the mask in a bag until you reach a venue that allows it.

Haunted houses and horror attractions

Universal Horror Unleashed is the one big haunt that doesn't depend on the calendar: Universal's permanent 110,000-square-foot venue in the AREA15 district runs four movie-grade houses year-round, with the HamiKuma takeover through October and Krampus & Kin from November. Tickets come in three tiers: an atmosphere-only ticket that skips the houses, a one-pass-per-house general admission, and an unlimited-houses tier. AREA15 lists it from about $69; expect Halloween-week nights toward the top of the range. It's recommended for ages 13 and up, under-18s need an adult, and operating days have shifted during 2026, so check the October calendar before you commit.

Zak Bagans' The Haunted Museum, in a 1938 mansion on the edge of downtown, is the other year-round option: a guided two-hour walk through 30-plus rooms of allegedly cursed objects, ages 12 and up, photos banned, Wednesday through Monday 10 a.m. to 8 p.m. Time slots sell out on weekends, so book one rather than walking up, and check the calendar for October 31 itself before you plan around it.

Freakling Bros, the valley's long-running independent haunt, sat out 2025. As of September 2, 2026 its official site says only "returning in 2026", with no dates, houses or tickets posted, so don't build a night around it until they appear. The seasonal pop-up haunts announce late, usually in late September and October, and none had 2026 dates as of this writing.

Shows and concerts that fit the night

A 1958 zombie nightclub is the obvious Saturday-night booking. Zombie Burlesque plays the V Theater at Miracle Mile Shops at 8 p.m. on both October 30 and 31: 75 minutes of comedy-horror cabaret, ages 16+, promo seats from about $39, and the identical show from the $110 rows, so buy cheap.

The concert calendar is stronger than most Halloweens. Mary J. Blige's "My Life, My Story" residency plays Dolby Live at Park MGM on October 30 and 31 at 8 p.m., from about $133 with fees. Earth, Wind & Fire close their nine-show Venetian Theatre run on October 30 and 31 at 8:30 p.m., face from $65 plus fees. Both price their weekend dates above midweek, and these are weekend dates.

The Wizard of Oz at Sphere has screenings on October 30 and 31, 2026, including an 11 a.m. and afternoon shows on Halloween day, which makes it the one big-room daytime option before the parties start. Sphere hadn't announced anything Halloween-specific as of September 2.

Halloween with kids in Las Vegas

Two family events have 2026 dates posted. HallOVeen at the Magical Forest, Opportunity Village's park at 6300 W. Oakey Blvd., runs October 2–4 and October 9–31: Sunday to Thursday 5:30–9 p.m., Friday and Saturday 5:30–9:30 p.m., so Halloween night itself is open until 9:30, with the box office closing 30 minutes earlier. Admission was reported at $24 when tickets went on sale in August, children 3 and under are free, and it covers the rides, the train, mini golf, the carousel and the trick-or-treat stations. Tickets are date-specific for the first time in 2026, so pick your night when you buy.

Haunted Harvest at Springs Preserve is October 22–25, 6 to 8:30 p.m., with members admitted from 4 p.m.: a family Halloween evening in the gardens at $14 for non-members and $8 for members, ages 3 and up, with 2 and under free. Tickets are online only, for a set date and time, and it's expected to sell out, so buy early. The venue is cashless, screens with metal detectors, and bans full-face masks on adults; parking is free, with overflow at Meadows Mall. It ends the Sunday before Halloween, so it won't fill Halloween night itself.

For October 31 itself, the resorts and malls hadn't posted their 2026 trick-or-treat programs as of September 2; they typically appear in October. Finish the kid program by 7 p.m.; the Strip and Fremont Street both turn into an adult party by 9. More in Las Vegas with kids.

Weather, timing and money

Late October is close to ideal: the normal high on October 31 is 74°F with a normal low of 54°F, the record high for the date is 86°F, rain is rare, and the sun sets at about 5:47 p.m., so the canopy's first light show plays in full darkness. A costume that works at 8 p.m. needs a layer by midnight. With the clocks falling back at 2 a.m. on November 1, bars and clubs run a 25-hour Halloween night.

A Saturday Halloween prices like a holiday weekend: expect weekend hotel rates with an event premium on Friday and Saturday and a sharp drop from Sunday, November 1. Book rooms and the big-ticket parties by early October; the Ball sells in early-bird tiers that only go up, and the club headliners follow the same curve. Plan for rideshare surge pricing downtown after midnight.
