Halloween falls on Saturday 31 October this year, so most offices will celebrate on Friday 30 October. That gives you about two weeks. The best office Halloween parties are short, easy to join and built around three things: costumes, food and one or two good games. Here's how to plan one your team will remember.
When to hold it
- Friday 30 October: the most popular choice. Costumes on the last working day before Halloween, and everyone heads into the weekend in a good mood.
- Thursday 29 October: better if a lot of the team works from home on Fridays.
- Lunch or late afternoon: a costume lunch (12:30–2:30 pm) or a party from 4 to 6 pm gets the most people. Nobody has to stay late, and remote colleagues can join the costume parade on a video call.
Costumes: easy, optional and work-friendly
Costumes are the heart of an office Halloween party, but not everyone wants to dress up. Make it optional and give people an easy way in.
- Pick a theme: movie villains, dress as your favorite emoji, horror-film classics, or office in-jokes (the printer that never works, the meeting that could have been an email).
- Offer a low-effort option: a single accessory counts. Cat ears, a witch hat or a pumpkin tie is enough to join in.
- Put simple rules on the invitation: nothing gory or offensive, no masks that hide faces at reception, and no costumes based on other cultures or real colleagues.
- Give small prizes: scariest, funniest, best homemade and best team costume.
Food: ask first, then plan
Whatever you choose, start by asking. A Halloween spread for 60 people has to work for vegetarians, vegans, people with nut, gluten or dairy allergies, and the colleague who's off sugar. Collect everyone's food preferences with the RSVP, then plan the food around real numbers instead of guesses.
Option 1: The office orders the food
- Share the numbers with the caterer: how many veg, non-veg and vegan plates, and which allergies to avoid.
- Keep it themed: pumpkin soup, mummy spring rolls, a black-bean graveyard dip, orange and black cupcakes.
- Order about 10% extra for walk-ins and second helpings.
- Label every dish with its spooky name, what's really in it, and any nuts, gluten or dairy.
Option 2: A team potluck
- Split by course. Give each team a category: savory snacks, mains, sweets or drinks.
- Give every dish a spooky name. Witch-finger breadsticks, monster momos, graveyard brownies, with a card showing what's really in it.
- Plan around the preferences. If a quarter of the team is vegetarian or vegan, make sure a quarter of the dishes are too.
- Let people claim a dish on a shared potluck list, so you don't end up with six bags of candy and no lunch.
- Away that day? Still in. Colleagues who can't make it can still claim a dish and send it in with someone who's coming.
- The office covers the rest: plates, napkins, drinks, decorations and a big bowl of candy.
Many offices mix the two: the office orders the mains and every team brings a themed snack or dessert.
Fast Party handles both. Guest preferences collect veg, non-veg or vegan, allergies and drinks with the RSVP and show the totals on one screen, ready to send to a caterer. Going potluck? Create your event in Fast Party, invite the team, then turn on the Potluck Manager. Set the categories, your guests claim a dish, and you see what's covered and what's missing on one screen. Even guests who RSVP no can still sign up to send a dish.


10 office Halloween party ideas
- Costume parade and contest. A quick walk around the floor, then everyone votes. Remote colleagues join on camera.
- Decorate your desk. Each team gets a budget and an hour to haunt their corner. The best pod wins.
- Pumpkin painting station. Paint instead of knives: safer at work, and less mess on the carpet.
- Guess the candy count. A jar at reception all week, winner announced at the party.
- Mummy wrap race. Teams of three, one roll of toilet paper each, two minutes on the clock.
- Halloween quiz. Ten questions on horror films, Halloween history and the office, in teams of five.
- Murder mystery hour. Hand out roles the day before and solve a whodunnit over lunch.
- Photo booth. A dark backdrop, a few props and good light. Share the best photos in one album afterward.
- Desk trick-or-treat for kids. Colleagues' children walk the floor with bags. Desks that want to join put a pumpkin sign out.
- Best dish vote. If you go potluck, everyone votes for their favorite spooky dish. The winning team takes home a trophy (a painted pumpkin works).
Keep it safe and inclusive
- Not everyone celebrates Halloween. Keep costumes and games optional, and plan something everyone can join, like the quiz or the food.
- Use LED candles and battery lights. No real flames near desks or paper decorations.
- Keep fake blood, face paint and glitter away from laptops and carpets, and have wipes ready.
- Label every dish and every candy bowl with allergens, especially nuts.
- Families welcome? Say so on the invite. Guests add their kids when they RSVP, so you know how many trick-or-treat bags to fill.
Send an invitation people open
A designed invitation gets more replies than a calendar invite. Pick one of our Halloween templates:



Or browse all Halloween invitation templates.
Wording you can copy: "Join us for our office Halloween party on Friday 30 October, 4 pm, in the cafeteria. Costumes optional, prizes for the best ones. Please RSVP by Monday 26 October and tell us your food preferences and any allergies. Kids welcome for desk trick-or-treat at 4:30."
How to run your office Halloween on Fast Party
1. Create the event
Pick a Halloween invitation, then add the name, date, time and place, and the costume rules.




2. Turn on guest preferences
Everyone answers veg, non-veg or vegan, allergies and drinks with their RSVP, and you see the totals on one screen.


3. Invite the team
Share a link, put the QR code on the office screens, or add people directly. Colleagues RSVP in a tap and say how many adults and kids are coming.




4. Plan the food from the totals
Send the numbers to your caterer, or turn on the Potluck Manager so your guests claim a dish. Guests who can't come can still send one in.
5. Watch the RSVPs
See who's coming at a glance, and send one reminder to people who haven't replied.


6. Let guests check themselves in
Turn on Check-In and guests check themselves in when they arrive, so you know exactly how many people are at the party. It's the accurate count you need for the costume vote, the candy bags and, at a restaurant or venue, the final plate count. Guests do it themselves once you, the host, turn it on.


7. Share photos
Add the best costume photos to one shared album, so the whole office can see them.


8. Open Feedback Corner
Send a 2-minute survey the next day, so next year is even better.

Frequently asked questions
When is Halloween in 2026?
Halloween is on Saturday 31 October 2026. Most offices celebrate on Friday 30 October.
Does everyone have to wear a costume?
No. Keep costumes optional and let a single accessory count. Plan games and food that everyone can join, dressed up or not.
Should the office order the food or run a potluck?
Either works. Ordering is easier for big teams and tight timelines. A potluck costs less and gets everyone involved. Many offices do both. In every case, collect food preferences first and plan from the numbers.
How do we keep an office Halloween party inclusive?
Make costumes optional, set simple costume rules, skip anything gory, label food for allergies, and include remote colleagues on a video call for the parade and the quiz.
How far ahead should we plan an office Halloween party?
One to two weeks for a party in the office. Send the invitation at least a week before, so people have time to plan a costume and you have everyone's food preferences in time.
Bottom line
Pick the day (most offices: Friday 30 October), keep costumes optional, ask everyone's food preferences with the RSVP, then order the food or run a potluck from the numbers. Start with the Office Halloween Party invitation and keep the RSVPs, preferences and reminders in one place with Fast Party.
