Here’s what to expect from this post:

  • How we transformed our family Halloween party into a Harry Potter Halloween Party (rain and all)
  • DIY party zones: Great Hall, Platform 9 3/4, Forbidden Forest, and more
  • 20+ decor ideas, props, and food to help you throw your own themed bash
  • Affordable supplies and tips for creating a magical vibe
  • Links to tutorials, recipes, and some of our favorite details from the night

Colleen, Fatima, and I are our family’s biggest Harry Potter fans. When the books launched in stores, my mom, Colleen, and I would wait outside for hours until midnight just to get our copy. Meanwhile, Fatima’s family had the right idea: walk into the local supermarket, grab a book, and head home. No lines, no chaos. Just straight to reading.

Even now, if one of the movies is on TV, we’re watching—DVDs on the shelf or not. And we’ve all been lucky enough to visit the Wizarding World of Harry Potter at Universal Orlando. Like millions of people around the world, we love the franchise. So I honestly don’t know why we waited so long to throw a Harry Potter-themed party.

This year, we finally did it.

DIY Harry Potter Party

Last weekend, Fatima and I headed back to Connecticut for my family’s annual Halloween Party. We’d been planning the Harry Potter theme for weeks. With 80 RSVPs, our plan was to spread the party across the yard and house. But nature had other plans. It rained nonstop. So we had to call an audible and bring the magic indoors.

We split the house into Hogwarts-inspired spaces:

  • The Great Hall for food, drinks, and floating candles
  • 4 Privet Drive in the living room
  • The Forbidden Forest in the hallway
  • And Platform 9 ¾, reimagined in the entryway

One of the garages became our makeshift beer garden (last year it was outdoors). We merged it with the Hogwarts Castle backdrop and pong tables. Honestly? It worked even better than expected.

We went all in on the DIYs. Here’s what we made:

1. Hogwarts Express

Colleen built this incredible cardboard train. It was the first thing you saw when you walked in.

2. Hogwarts & Forbidden Forest Signs

Made in Pages using the Harry P font. Easy and effective.

3. Patronus Stag & 4. DIY Dementor

The Patronus was actually a repurposed Christmas reindeer, and the Dementor? A skeleton wrapped in black cheesecloth. Creepy in the best way.

5. Hogwarts Castle

Colleen painted this on cardboard as a pong/flip cup backdrop. It looked awesome in the garage setup.

6. Sorting Hat

A gift I gave Colleen a few years ago finally got its moment. Bonus: it now sits on top of her Christmas tree every year.

Plastic brick backdrop + a truck + old suitcases = the perfect Instagram spot.

We found these signs here, printed them, and scattered them around the house.

10. Floating Candles

This was one of the most magical setups. Once it got dark, the sunroom truly transformed into the Great Hall. Tutorial for the candles here. Something I wish we had for this party… get yourself these floating candles for your Harry Potter themed party!

11. Golden Snitches

Ferrero Rochers and DIY wings from Bite Sized Biggie.

12. Pumpkin Bisque

Just a great dish to serve at any fall or Halloween party. This rocked.

13. Butterbeer

The best non-alcoholic Butterbeer recipe we’ve had! It’s not a copycat of Universal’s, it’s better. Not too sweet, just right. We quadrupled the recipe and filled shot-glass-sized cups up so everyone could have a taste.

14. Chocolate wands

Pretzel rods dipped in melted chocolate with sprinkles. Kid-approved.

BONUS: A Harry Potter Party Birthday Cake

Yes, we even had a Harry Potter birthday cake. Because why not?

This party took a lot of planning, but it was one of the most fun and immersive Halloween themes we’ve ever pulled off. If you’re a fellow Potterhead, a themed bash like this is a must at least once. Rain or shine.

Let me know if you want a printable checklist or supply guide for your own Harry Potter Halloween Party—happy to put one together!
