Your 30s are a time for coming into your own as an adult, finding your place in the world, and in general, feeling more comfortable in your own skin as your confidence grows. Considering how important a milestone a 30th birthday is, we’ve put together a list of 20 creative 30th birthday party themes that’ll go a long way toward your party planning.

As you go through this big list of themes, imagine what your ideal birthday party venue might look like. Then, take a look at Peerspace—which is the largest online marketplace for hourly venue rentals—to discover the best birthday party venues the platform has to offer in your area.

1. Wow your guests with a monochromatic theme

First on our list of creative 30th birthday party themes is a concept you might not have considered: a monochromatic party, meaning a party where virtually everything is a single color (or varying shades of the same color). In addition to keeping your decor within these color parameters, you can also ask your guests to dress entirely in the color of your choice for extra fun. Check out how TikToker @am0re.c executed this birthday party theme in all white.

2. Plan a timeless enchanted garden party

How about a birthday party inspired by the aesthetic of a beautiful, magical garden—something out of a fairytale? If you want to feel like a princess, it’s hard to go wrong with this 30th birthday party theme. Here’s how @eventsbyelle made this a reality (for a Quinceañera, but it’s a great example nonetheless).

3. Embrace a 70s disco theme and dance all night

All you really need to make a 70s disco theme a reality are some disco balls and some fabulous disco tunes, but if you want to go all out, creative decor and lots of colored lights will take it to the next level.

4. Keep it stylish and simple with a flower-arranging theme

This flower-arranging party activity/theme means you won’t have to go to the trouble of finding decor, activities, or party favors for your guests—the bouquets can fill all three roles! We think this is an especially great choice for a spring birthday, but flowers are a mood lifter any time of year.

5. Be super chic with a black-and-white themed party

For some seriously chic vibes, how about a black-and-white party? Once again, we’d recommend that you ask your guests to come dressed in black, white, or a mix of both to really make the theme pop.

Here are some super chic black-and-white party ideas to theme every aspect of your birthday party!

6. “Dress as the first letter of your name” costume party

Don’t just tell your guests to come in costume for this themed costume party. Give them an extremely specific prompt for their costumes, and see how creative they can get with it!

7. Get sleuthy with a murder mystery party

Although a murder mystery party theme requires a bit more planning than most to prepare a truly challenging and intriguing mystery for your guests, the end result is so worth it—happy guests who’ve made plenty of memories as they work to puzzle out the solution together.

8. Make it bubbly and golden with a champagne brunch

Seeking elegance and festive vibes? Love breakfast foods and going out to brunch weekly? Then throw a champagne brunch for your 30th!

9. Make it a party based on all your favorite things

Naturally, everyone’s list of favorite things will be a little different, so we can’t make any blanket recommendations regarding a favorite things birthday theme. The gist is to pick out your favorite things and make them the focus of your party! For instance, if you’re obsessed with bulldogs, bagels, and tennis, incorporate all of those into your party theme.

10. “Dress like it’s your birthday” dinner party

Normally, for a formal birthday party, guests will mostly avoid dressing up too fancy to avoid outshining the person celebrating their birthday (who should really be the star of the show). You can turn this concept on its head entirely by actually asking your guests to come to your birthday dinner party dressed up in the outfits they’d wear if it were each of their birthdays. So much fun!

11. Host a throwback, grown-up sleepover

Now this’ll up the nostalgic vibes — throw a sleepover birthday party with all your besties, just like you might’ve done for your birthday when you were half your current age!

12. Delight your inner nerd with a video game tournament

If you love playing video games with your best buds, make this the focus of your 30th birthday. Whether you choose Mario Kart, Call of Duty, or another game entirely, the competitive aspect will make this a night to remember.

13. We’ll always wager on a casino night party!

Or if you like a little friendly competition but are not one for video games, how about a casino night-themed party?

14. Promote personal wellness with a spa and self-care day

No need to head to an actual spa to spend the day pampering yourself with face masks, refreshing snacks, and relaxing music.

15. Travel to your dream destination

Where have you always wanted to visit in your 30s? Paris? India? The Caribbean? Make this coveted destination the focus of your party!

Saying “Oui!” to a Paris-themed party? We can help you out further with our fabulous Parisian-themed party ideas!

16. Pool party

For a summer birthday, give your guests a chance to cool off in style with a pool party. Even if you don’t have a pool of your own, it’s easy to rent a pool in your area through Peerspace.

17. “RIP to my 20s”

For 29-year-olds with a hilarious sense of humor—and a willingness to laugh at themselves—an “RIP to my 20s” party theme will be an absolute hit.

18. Get on your feet for a karaoke birthday party

Love performing, or watching your friends belt out their favorite songs? Make karaoke the focus of your party! (You could also incorporate karaoke as an activity into any of the other themes on this list if you’d prefer.)

19. 13 Going on 30? We know the feeling!

If you have fond memories of watching 13 Going on 30 when you were younger, commemorate those nostalgic feelings by throwing a 13 Going on 30-inspired birthday party!

20. Be a Barbie princess today and always

Did you see the Barbie movie in the summer of 2023 and feel inspired and moved to tears the whole time, like we did? Then have a Barbie princess-themed party for a unique option that’s not quite your run-of-the-mill Barbie party, but that’s still hopping on this incredibly fun, bright pink-infused trend.
