A Mayfair Halloween party is the dressed-up version of London's biggest club weekend, and Halloween 2026 falls on Saturday 31 October. The Arts Club on Dover Street throws one of Mayfair's best-known Halloween parties, but it is a private members' club: this guide explains who can go, then sets out the Mayfair clubs you can actually book for Friday 30 and Saturday 31 October, with costume and timing advice.

Can you go to The Arts Club Halloween party?
The Arts Club is a private members' club at 40 Dover Street, founded in 1863 and still built around members from the art, music and creative worlds. Its Halloween party is for members and their guests. There are no public tickets, and the only way in is an invitation from a member.
Mayfair Nights books Mayfair's nightclubs. We do not sell entry to The Arts Club, and nobody honest can promise you a place at a members' club party. As of 7 October 2026 the club had not published anything about its 2026 Halloween.
The Arts Club Halloween in past years
For context only, not a guide to 2026:
- 2021: artists dead or alive. Members came as their favourite artists, thinkers and musicians, with Van Gogh, Salvador Dali, Frida Kahlo, Andy Warhol, Freddie Mercury and Marilyn Monroe among the costumes. The decor stayed restrained, with a Van Gogh tombstone as one of the few set pieces, and left the spotlight to the guests.
- 2019: a live line-up featuring The Fellas, Tasty Lopez and Rebecca Freckleton plus DJs, with costumes worn over the club's usual smart dress.
The common thread is that the costumes are the show. That is a useful brief for any Mayfair Halloween party.

Not a club person? Other Mayfair Halloween options
Not every Mayfair Halloween needs a table. As listed on DesignMyNight as of October 2026, Mr Fogg's Residence on Bruton Lane runs a Halloween Murder Mystery on Saturday 31 October, from about £63 with two cocktails. It works well as an early-evening start before a club.
London Halloween costume ideas that work in Mayfair
Mayfair doors still apply their dress codes on Halloween. Tape and Cirque le Soir, for example, list heels and a dress for women and smart clothing for men as standard, as of October 2026. Costumes that work:
- Dressed-up concepts: a famous artist, a film villain in black tie, a gothic ballgown, a vampire in a tailored suit. The Arts Club's artist theme is a ready-made idea.
- Face paint over full masks: you must show your face to match your photo ID at the door.
- Smart shoes: costume or not, trainers can still be refused at Mayfair doors.
- Light props only: realistic weapons will not get past security, and large props go to the cloakroom.
How to plan the night
- Book early: Saturday 31 October is the busier night; Friday 30 October usually has more choice.
- Arrive early: aim for 11pm to midnight, before the door gets selective and the queues build.
- Getting home: the Saturday Night Tube runs on the Victoria, Piccadilly and Jubilee lines through Green Park, the nearest stop to Dover Street.
