18th Birthday Party Ideas

Before we get to all the party details (decor, games, etc.), here are the most popular 18th birthday party ideas to get your inspiration going!

Take a Birthday Vacay

This is my favorite 18th birthday idea if your budget allows! A birthday vacation is a great way to celebrate with a few of your closest friends and make memories that will last a lifetime.

Whether you opt for a dream destination or just spend the night in a nearby city, you’re sure to have a blast.

Plan a Themed Party

This is always a fun one. Choose a party theme and invite all of your friends for a night to remember. Get decorations from Amazon or Etsy, or DIY them yourself.

Some fun 18th birthday party theme ideas include Gatsby theme, disco party, black tie party, casino night, bohemian party, ’80s theme, Coachella theme, slumber party, tropical party, glow in the dark party, beach party (if it’s summer or you live in a warm climate), white party, neon party, and rainbow party.

Karaoke Night

You may not be old enough to go to a karaoke bar yet, but you can totally host your own karaoke night at home for your 18th birthday!

This is the perfect 18th birthday party idea if you and your friends love music, and it’s so easy to set up at home.

All you need is a karaoke microphone (this rose gold one from Amazon is so cute), a TV or laptop, and maybe a disco ball light for ambience (this one is less than $15). Then just cue up some Youtube karaoke videos and you’re good to go!

Scavenger Hunt

A scavenger hunt is a really popular 18th birthday party idea right now and there are so many ways to do this one!

I love the idea of getting some printable scavenger hunt clues from Etsy and finding a really great prize, like scratch tickets or a gift certificate to everyone’s favorite restaurant. This will amp up the competition and get everyone excited to play along.

You can combine this with some of the other party ideas on this list as well!

Pool Party

Pool party

I have a summer birthday so this is always one of my go-to party ideas.

If you have a summer birthday, this is an easy go-to, but you can also do it in winter if you have an indoor pool or live near one you can rent out. The fun basically takes care of itself so there isn’t a ton to plan!

Retro Roller Skating

Retro roller skating party

Roller skating rinks are still a thing and if you have one near you, definitely consider it for your birthday party! You and your friends can dress up in retro styles (hello vintage shopping), eat pizza and snacks, and roller skate to your favorite music.

Most roller rinks will allow you to rent them out for parties and most have party packages to make your planning super easy. You will get the coolest Instagram photos and have an absolute blast.

Hotel Party

This is kind of similar to the trip idea above but you do it in your own city. It’s always fun to get away for the night, so have a group of your friends chip in to rent a room or suite at a nice hotel in your area.

Go to dinner at the restaurant at the hotel, then head back to the room. Stay up late, wear matching pajamas, watch movies, and order dessert from room service. Maybe even hit up the spa and swim in the pool. A perfect low-key but glam birthday party idea.

Fancy Dinner Party

I love the idea of a fancy dinner party for an 18th birthday! It’s so grown up and chic, and it’s a really intimate way to connect with your best friends.

If you love to cook, think up a menu that will be fun and easy for you to prepare. Alternatively, you could get fancy and have dinner catered! Or do a potluck with your friends for an easy option. No matter what, you’ll have a blast.

Outdoor Movie Night

This idea is perfect for the warmer months or if you live in a warm climate in the winter. An outdoor movie night is a blast and you can share one of your favorite films with your friends.

To set up an outdoor movie night, you’ll need a portable projector, a screen, some chairs, and plenty of delicious snacks. I also love the idea of using string lights to really set the scene.

Amusement Park Party

This one is so much fun because although you’re now a legal adult, you get to act like a total kid again.

Disneyland or Disney World are super popular options for 18th birthdays but definitely pricey. You can definitely go to an amusement park that’s closer to home, like a Six Flags or even a water park in the summer months!

Again, many of these theme parks have party planning services to make your life super easy, so definitely find out if yours offers this.

Best 18th Birthday Decorations

There are so many cute decorations out there made especially for 18th birthdays so here are some of the best ones, all CF-approved.

18 and Adultish Banner

This one is too cute. It’s a simple banner that reads “18 and adultish” and since it’s neutral gold, it will literally go with any type of party decor. Plus, it’s super affordable!

DIY Photo Booth

DIY photo booths are super popular at 18th birthdays and they’re incredibly simple to set up.

I love these rose gold 18th birthday balloons from Etsy! As opposed to your typical giant “18” number balloons, these ones are clear with rose gold confetti inside! More unique and so pretty.

18th Birthday Confetti

Confetti is always fun, so why not get yours in the shape of the number 18? You can never have enough glitter if you ask me, so this gold glitter confetti is perfect.

18th Birthday Tiara

An 18th birthday is a great chance to go over the top with your outfit, so why not rock a tiara? Honestly, have fun! This one from Etsy is super cute and affordable.

Rose Gold Glitter 18th Birthday Table Decoration

Minute to Win It was a popular TV show a while back, and while the show isn’t on anymore, “minute to win it games” are super popular at parties!

Pick Your Poison Game

I have never played Pick Your Poison but when doing research for this article, I saw this mentioned a lot for 18th birthdays.

Basically, Pick Your Poison is a “Would You Rather” game that focuses on wacky combinations (e.g. “never see the sun again” or “live without music”). It’s sure to spark tons of interesting conversations and get your friends talking. There’s also an adult edition if you want to get wilder.

Birthday Girl Trivia Game

How well do your friends know you? Test them with a custom birthday girl trivia game. You can buy a printable game on Etsy to make it super easy.

The prize can be similar to the scavenger hunt idea above — you could go for scratch tickets, a gift certificate to a favorite restaurant, or even something fashion related like a Nordstrom gift card.

We all have smartphones, so we might as well put them to good use! There are so many virtual games you can cue up during your party that are so much fun.

Some of my favorite virtual party games are Heads Up, Who Can’t Draw, and Psych!

This makes the party games super easy. You can download a whole birthday party games bundle on Etsy that has tons of cute game ideas based around the birthday girl.

Incohearent Party Game

From the makers of the popular party game What Do You Meme? comes Incohearent, a game that has you decoding gibberish with hilarious results.

The game gives you cards with gibberish phrases that are actually pop culture names, and everyone has to guess. This will definitely have you laughing!

Cards Against Humanity is a total classic adult party game that honestly never fails to get everyone laughing.
