Let loose this year with these unique and exciting birthday party ideas for adults! You are never too old to have the ultimate birthday party celebration. Forget “adulting” for one day and party with your friends and family for an adult birthday bash.  

Throw a cocktail party. 

Experiment mixing cocktails at someone’s home or rent a private room in a cocktail lounge and have a fancy evening out.  

Have a spa day.  

Spend the day at the spa and get some much-needed R&R. This adult birthday party idea lets your party guests spend time together relaxing and detoxing.  

Charter a yacht or party on a booze cruise.  

Splurge on a luxury birthday party across the open water. Watch the sunset and toast to another year of friendship and laughter. Your birthday only comes once a year, so start off another year older with an incredible adventure.  

Plan a murder mystery dinner party.  

Have a killer adult birthday party, featuring dinner and a murder. Ask guests to dress ahead of time and give each person a character description. At the party, guests mingle to learn about each other. When the murder occurs, it’s up to you to figure out who dunnit! Place your bets and discover the murderer at the end of the night. Party guests can also win small prizes for best dressed, best acting, etc.  

Host a bake swap and games night.  

Ask guests to bring a baked good to share with everyone. Swap treats and play board games through the night.  

DIY a themed bar crawl.  

Bar hop to your favorite places for a drink with friends—but make the night unforgettable with a fun birthday party theme! Party like it’s the 80’s and dress in clothing from the decade. Plan a Harry Potter bar crawl and ask guests to dress up like characters from the Harry Potter films. If you have a birthday around Halloween, make a ghoul of yourself at a zombie pub crawl with full zombie makeup.  

Set up a gourmet burger bar and beer making party. 

This adult birthday party is all about eating and drinking all day long! Set up a table with gourmet burger toppings (pineapple, maple bacon, spicy coleslaw, sautéed mushrooms, homemade guacamole) and let birthday party guests build their own gourmet burger to their taste. Then wash it down with homemade beer. Party guests can all participate in a beer making party in the garage. There’s nothing better than drinking a beer you brewed yourself! Guests can take home the extra bottles as adult birthday party favors (or keep them on hand for your next football game-day party). 

Enter your birthday party guests into a trivia night.  

Make a reservation for trivia night at a local bar or restaurant and enter birthday party guests as a trivia team. Pick a favorite theme night—like Star Wars, Disney, or Big Bang Theory—and get ready to crush the competition over drinks and appetizers.  

Throw a birthday party casino night.  

This birthday party for adults brings Las Vegas to your home and requires little set up. Ask birthday party guests to dress in their finest gambling attire and sit at tables arranged for poker play.  

With the party planning in full swing, you’ll also want to think about birthday gifts. Here are some birthday gift ideas for adults that are thoughtful and “wow-worthy”. Check out our recommended birthday gift ideas for adults.
