Halloween is quickly approaching — are you scrambling to decide what your costume is going to be this year?

Which group do you fit into?…

  1. You’re going out with friends trick-or-treating together (or attending the same party).
    – OR –
  2. You’re going out with family members for a Halloween event.

One of the most fun things you can do to celebrate Halloween as a group is to all dress up around a theme — so that your costumes go together!

Following are over 250 themed Halloween costumes for groups of all sizes, ages, and genders.

And if you’re a DIYer (or a last-minute Halloween costume planner), I have some good news… Most of these Halloween costumes for groups can easily be made yourself using items you already have at home!

Of course, if you still have a few days to get your group costumes ready (or you’re not exactly the creative type), then you can also find many of these online — ranging from same-day to 2-day shipping.

Below, you’ll find the most clever themed Halloween costumes for:

  • Males and Females
  • Adults and Kids
  • Groups of 3 or More

BONUS: If you use Pinterest, you can click on each one to see the best photo and/or tutorial for making the costume yourself! If you don’t have a Pinterest account, then use this list as inspiration for group costume ideas and Google will provide you with plenty of examples. You see, I initially created this mega list of 250+ ideas purely as a source of inspiration for my own group costume ideas — because I had all of these ideas swimming in my head that I figured many people wouldn’t think of. Then, for future reference for myself, I saved each one to a Pinterest board that I created and called DIY Halloween Costume Ideas (500+ pins and counting). So, the how-to links are there if you want them.

Okay, here we go… my picks for 250+ of the best Halloween group costume ideas!
