If you’re in the United States, turning 18 means becoming a legal adult—with all the rights and responsibilities that status entails! We’d say that’s more than worthy of an extra special birthday celebration. To help you plan it, we’ve assembled a long list of 18th birthday party themes that’ll make your transition to adulthood a memorable and meaningful one.

As you consider our list of suggestions, ask yourself what your ideal party venue would look like, and what amenities it would offer. Once you’ve chosen a theme, visit Peerspace—the largest online marketplace for hourly venue rentals—to see what kind of birthday party venues are available in your area.

1. Live it up with a disco dance party

The 70s are back—so how about a disco-themed dance party? This top-notch 18th birthday party theme does require space for a dance floor, so if you don’t have that already, you can rent a venue for a dance party near you on Peerspace.

2. Create your own Barbie world for a day

2023 was the summer of Barbie, but the fun definitely doesn’t have to end there. Throw a Barbie-themed birthday party for a playful gathering that shows you’re never too old to enjoy tons of hot pink.

3. Get creative with a PowerPoint presentation party

Ask all your friends to make PowerPoint presentations—about you, or just on a topic they enjoy—and present them to your guests! This is such a cool and creative idea, and we absolutely love it.

4. Make it a 90s-themed birthday party

If you’re turning 18 soon, you’ve never experienced the 90s, but that doesn’t mean you can’t appreciate the decade and throw a 90s-themed party! Put together a playlist of your favorite 90s songs and ask your guests to wear their best 90s-inspired outfits.

5. Get nostalgic with a Shrek party theme

A Shrek party theme has the potential to be seriously hilarious. If having a blast is a priority on your birthday and you’re not as concerned about everything having the perfect aesthetic, go for a Shrek-themed birthday!

7. Dazzle your guests with a tasty BBQ party

Love to hang out outside with friends and eat BBQ classics like hamburgers and hotdogs? (You can also get a lot fancier with this, of course.) Plan a BBQ in your backyard!

8. Get everyone in on the cooking with a potluck dinner

Maybe you want to have a variety of delicious food available for your party guests, but you don’t want to spend hours or days cooking (or hiring expensive caterers). Throwing a potluck where everyone brings their favorite dish is an ideal solution.

9. Brunch: a classic for a reason!

Brunch tends to feel a little more casual than dinner, so a brunch party theme is a great alternative if laid-back vibes are a priority for you. Not to mention that brunch food like omelets and waffles are to die for!

10. Go sophisticated with a Breakfast at Tiffany’s theme

If you’ve ever watched Breakfast at Tiffany’s and admired Audrey Hepburn’s elegance and pizzazz, consider making this the theme of your party.

11. Go to the ends of the universe and back with a Star Wars theme

If you’ve always wished you could grow up to be a Jedi, allow yourself and your friends to pretend for a night with an epic Star Wars-themed birthday party.

12. Create a DIY escape room challenge

Set up an escape room with a variety of themed puzzles and challenges for your guests to solve collaboratively! By the time they’re done, they’ll have gone through a genuine bonding experience.

After you’ve picked a theme, plan the rest of your party using our 18th birthday party ideas as your template!

13. Have a blast with a retro arcade theme

Transform your venue into a vintage arcade with classic arcade games, neon lights, and nostalgic snacks and drinks.

14. Steal the spotlight with a karaoke party

Sing your heart out and enjoy being the star of the show for a night at your very own karaoke birthday party. Just make sure you’re in a space where you’re allowed to make some noise and you won’t be disturbing the neighbors too much! If you’re concerned about getting too loud, you can always avoid the risk entirely and make things easy by renting a karaoke bar near you on Peerspace.

15. Explore good and evil with a superheroes and villains party

If you love superheroes and comic books, invite your guests to come dressed as their favorite superheroes (or villains!), and be sure to put up decorations and activities that suit the theme.

16. Make it a glamorous Hollywood affair

Roll out the red carpet and give yourself and your guests the celebrity treatment with a glamorous Hollywood-themed party!

17. Splash around with your own pool party

If your birthday takes place when the weather is warm, you truly can’t go wrong with a pool party. This is another case where, if you don’t have a pool of your own, Peerspace makes it easy to rent spaces with pools near you to execute this awesome 18th birthday party theme.

18. Ramp up your skills with a cooking class party

Hire a professional chef to come to your party and teach everyone how to cook a dish of your choice! It’s a great and highly practical choice for an 18th birthday party theme because becoming an adult means learning to feed yourself, among many other responsibilities.
