7 Office Halloween Party Ideas

October is here and that means that Halloween is just around the corner! Have you picked out your costume yet?

Hosting an office Halloween party is a great way to bring your team together and get into the spirit of the season. Whether you choose to host a happy hour, costume contest, or simply decorate your office – adding some spooky vibes to your office can be a fun way to break out of the everyday routine of your work week!

If you don’t know where to start, having a theme for your office is a great way to build camaraderie and host an outside-of-the-box party! We have put together a list of our favorite office Halloween party ideas to get you in a spooky mood and inspire a party of your own.

Barbie’s Haunted Dreamhouse

This Halloween, think pink! Now a blockbuster movie, this iconic toy is a clever way to bring pop culture references into your office this Halloween.  

Encourage your team to come as their own Barbie, or reference an iconic Barbie of the past. Costumes could include: Astronaut Barbie, Malibu Barbie, Retro Barbie, and of course, Ken.

Transform your office into Barbie’s iconic Dreamhouse; pink candy, drinks, and décor is a must. Create Barbie posters with your team’s photos, like the popular meme from earlier this year.

For a spookier twist, turn Barbie’s Dreamhouse into a haunted house! Decorate with pink cobwebs, glamourous skeletons, and bejeweled bats.

Rock n Roll Hall of Fame

Rock out this Halloween with a music inspired office party! Encourage costumes that reference iconic musicians, past and present. Will you be punk or pop? Country or classic jazz?  

Get everyone involved with a karaoke party or lip sync battle. Make a shared playlist for your office and let everyone get a chance to DJ throughout the party. This theme is sure to be a chart-topper.  


Go back in time with one of the most classic office Halloween party themes! Reference iconic characters, major moments, or defining styles that take inspiration from a recent decade.

If your office has multiple teams, encourage a competition for group costumes themed to different decades. Hold a fashion show or create a competition for the best recreation of a classic style. This timeless theme is fun for everyone and an easy costume to thrift or find online.


Put a spin on the classic murder mystery board game with a color-coordinated costume party this Halloween. Dress as a monochromatic character from the game or come up with your own color inspired character. Will you be pulling out the purple as Professor Plumb or slipping into something red for Miss Scarlet?  

Take this party to the next level by hosting an office murder mystery party. Use a pre-planned script or write your own to customize the game to your own team!


Surprise your office with some on-site PTO! Take your office on an exotic vacation with a vacation themed Halloween party.

Encourage costumes inspired by different vacations: are you traveling to the snow? To a tropical island? The coast of Italy? A safari? Let the creativity flow with this resort-wear inspired office Halloween theme.

History: Back From the Dead

It’s night of the living dead, with a historical twist! Bring your favorite figures from pop culture and history back to life with an office Halloween theme for the ages. Will you be Marie Antoinette, Cleopatra, or Elvis? Time is in your hands with this classic Halloween theme.

A Night at the Oscars

Hit the red carpet with a star-studded office Halloween party. Come as your favorite movie or TV show character and see who will take home the Oscar for Best Costume. Screen movies throughout the day and host a movie and TV trivia competition for a prize.
