Las Vegas will get a spooky (and swingin’) Halloween this year: The Mob Museum is throwing a free Halloween Party on Saturday, October 31, 2026, turning its downtown campus into one unforgettable night of Prohibition-era revelry, live entertainment, and spirits — both the cocktail and supernatural kind.
The party runs from 7 p.m. to midnight at the outdoor Starlight Plaza and from 8 p.m. to midnight inside The Underground speakeasy and distillery. Coco and The Sidecars will bring roaring ’20s jazz to Starlight Plaza, Amanda King and Her Prohibition Three will perform inside The Underground, and magician Nick Stone will add a little mystery to the night. Guests can sip specialty craft cocktails and mocktails while exploring the museum’s grounds after dark.
Best of all, the party is completely free to attend. Want to step inside The Underground? Just give the guy on the inside the password: SPELLS & SPIRITS. Guests must be 21 and over; the event is weather permitting. The Halloween weekend also brings special cocktail flights to The Underground from October 30 through November 1, with names like Flight of the Damned and The Poisoned Rose.
The Mob Museum, a 501(c)3 nonprofit dedicated to advancing public understanding of organized crime’s history, sits at 300 Stewart Avenue in downtown Las Vegas, steps from Fremont Street.
