2. Let everyone know that you’re 45 and feeling alive

You are never too old to have fun! Make light of your age with a funny elderly theme for your party. Ask guests to come wearing their best old man or old lady attire and tell them you’ll be partying it up with pudding snacks that go easy on the dentures. Then, dance the night away to organ music!

Stop by the thrift store before the party and pick up old wheelchairs, walking canes, and walkers and offer them to your guests as they walk in the door — then challenge them to a wheelchair race!

Book a vintage theatrical performance venue on Peerspace to serve as the perfect setting. If you’re in the Los Angeles area, then this vintage theater in downtown Inglewood is ideal! It has room for 50 guests and offers plenty of ambiance to highlight your festivities.

It also boasts rave Peerspace reviews from past renters like this: “Owen and Major were amazing! Super accommodating and helpful without being asked. Have been to several theaters and this is where I will always go back to from now on. No hidden fees and super friendly.”

3. Get nostalgic with a party that’s a blast from the past

Take a moment to reflect on the last 44 years with your friends and family during your 45th birthday party! Hang up your favorite photos from years past and set up a photo area where you can recreate your favorite photos. This would be a fun party favor for friends to take home with them — especially if you took them using a Polaroid!

Need some inspiration? Then this Chicago, IL photo and video studio ought to do it. Since it’s a professional studio, you can even book a photoshoot there and have a sensational birthday photoshoot to celebrate the new milestone you’ve reached.

4. Reflect forward and ponder a beautiful future

Your 45th birthday ideas shouldn’t just be about reflecting on the past — they should also include forward-thinking reflections! What do you hope the next few months, years, and decades will bring? Have your party revolve around who you hope to become in the next ten years.

For instance, you can book this incredibly opulent Beverly Hills estate on Peerspace for your 45th birthday party and imagine how amazing your near future will be when you live somewhere similar! It has 4,000 square feet of luxurious open space and city views.

“One of our favorite rentals! Unbeatable views. Immaculate space,” shares a Peerspace reviewer. “Gigi and Adam are gracious hosts and very responsive. Repeat rental. Highly recommend!”

5. May the forties be with you

Looking for a fun theme to center your 45th birthday ideas around? How about a Star Wars theme? Sip on some Jedi Juice, munch on Trade Federation Taters, and cook up other Star Wars food ideas. At the party, have a contest to see who can make the best Death Star Watermelon carving. You’re never too old for a Star Wars birthday party!

To top it off, Peerspace provides you with access to a slew of spaceship sets you can rent for your party backdrop. It’s the best way to ensure the Force is with you!

6. Gettin’ groovy

People celebrating their 45th birthdays in 2024 or 2025 were born in the final year of the 1970s, good ol’ 1979, or the first year of the new decade, 1980! So why not center your birthday party theme around your birth decade? Host your 70s-themed party in a groovy house (like one of these) with funky decor and tons of fun 70s games (Family Feud, anyone?). Invite your guests to dress the part, and make sure to take lots of photos!

If you’re opting for an 80s-themed party, we think this classic arcade in St. Paul, MN is the perfect spot to host your retro party. Just imagine you and your friends in your fantabulous 80s outfits dancing to some classic 80s songs in this space!

7. Feed your inner child and serve your favorite childhood foods

What were your go-to snacks as a kid? Feed your inner child and get your party catered with your favorite throwback foods! Or find fun old-school snacks to stock the party with, like Push Pops, Hi-C, and Ding Dongs.

Are you a fan of cooking and baking? Then book a sensational kitchen space on Peerspace that doubles as a neat event venue. For instance, this Wicker Park gourmet kitchen (pictured above) houses a chef’s kitchen and sweet event space, too. This is one of those 45th birthday ideas that the whole gang will appreciate.

A Peerspace user who booked a birthday party here shared the following helpful review: “Laura and her team are amazing!!! We had the best experience and the space is beautiful. Everything was seamless – would highly recommend.”

8. Make it a surprise party for the birthday person!

If you are the party planner but not the birthday guy or gal, then consider throwing a surprise party! You can add any of the ideas on this list to the birthday fun. You are just adding in the element of surprise!

This is a great way to take the stress off the person whose birthday is coming up and pleasantly surprise them with a birthday celebration they probably always wanted but didn’t have the time or ability to plan themselves.

9. Young once, immature forever

Act your shoe size, not your age for your 45th! There are tons of fun 45th birthday ideas to make you feel like a kid again — rent a bouncy house, spend the day go-karting, or hang out with the animals at a petting zoo! Consider it a one-day vacay from your usual adult responsibilities. Today’s your day, and you can have fun however you want to.

10. Turning 45 is fine when you look 29!

You look great for 45! Celebrate how great you feel and how good you look with a photoshoot on your birthday. You can do a solo portrait shoot or invite your friends and/or family to be involved too. A fun option might be renting a gorgeous venue and treating yourself to a boudoir shoot.

11. Capture every moment of your birthday bash

Hiring a photographer doesn’t have to mean posing and portraits. In fact, consider hiring a photographer to come to your party to capture all the raw and real moments of your birthday! While you and your guests are enjoying themselves, they will stand behind the scenes and film all the special moments you may have missed or wish to never forget.

Consider buying items like confetti and bubbles for your guests to use, as they’ll make for great photos. You can also include a photo backdrop area with fun backdrops — don’t forget to get everyone together for a group photo!

12. Get artistic and pick up some new skills

We love the idea of 45th birthday ideas that keep you and your guests relaxed yet engaged. To achieve that perfect party ambiance, why not book a Peerspace flex venue and plan some fun activities?

You can rent a venue like this versatile outdoor enclave in Greenpoint, Brooklyn, and make use of the creative energy and spacious surroundings. It is a 2,500-square-foot outdoor space brimming with murals, woodworking, and special seating that will inspire you and your guests.

For instance, you can hire a private chef to cook for you and your crew. Or, you can invite an instructor to come in and teach you something you’ve always wanted to learn, like how to brew beer, tie-dye shirts, knit, etc. Learning a new skill in a fun and supportive environment is how we stay young, after all!

13. Or get crafty in a private event studio

Love crafts and want to make them a central part of your 45th birthday soiree? Then why not show off your handy skills when you book a Peerspace workshop and event space near you, somewhere beautiful you and your guests can gather and create? We especially love this intimate event studio in Las Vegas, NV as one suggestion.

It’s a bright and modern venue set inside a bakery (score!), with adorable decor and large tables for getting to work. Talk to the host about arranging a cookie decorating party, an ice cream party, or other fun sugar-fueled fiesta to delight you and your sweet-toothed guests.

14. Gaze at stunning vistas as you toast a new year

Sometimes, all you need for the perfect birthday is a stunning view and amazing company. Keep it simple by booking a retreat-worthy venue on Peerspace and gathering your family and friends to enjoy it together. One incredible option is this luxurious home with Columbia River views in Washougal, WA. It’s an amazing option for hosting a dinner party helmed by a private chef. After dinner, toast to another amazing year and many more to come while watching the sunset from the furnished deck.
