Are you a huge fan of the world-famous story by Joanne K. Rowling? Have you read the books several times and already know the films by heart? Then it’s time for a magical Harry Potter party. Immerse yourself in the fantastic world of your favorite characters for an evening and bring the magic of Hogwarts into your own home.
Whether you’re a big or little Potterhead, you’re never too old for a Harry Potter–themed party! Find out below what to keep in mind when planning, which snacks you absolutely should serve, which activities are simply a must, and much more.
Which invitation for the Harry Potter-themed party?
No Harry Potter party is complete without the right costume!
Whether it’s a children’s birthday party, Halloween party, or themed party, everything is much more fun with the right costume. Which roles have you and your guests always wanted to step into? Now’s your chance. At Kostümpalast, you’ll find a wide selection of officially licensed costumes.

Harry Potter
To portray the famous young wizard, you need a Gryffindor robe, a wand, round glasses, and—most importantly—a lightning-shaped scar on your forehead. It can easily be drawn on with makeup.

Hermione Granger
You just have to love her—the clever, likeable friend of Harry Potter. As the top student in her year, she is one of the most promising magical talents at Hogwarts. Her costume consists of a Gryffindor robe, a magic wand, and a hair clip. Her thick brown curls are her trademark, especially in the first installments.

Ron Weasley
He completes the famous trio of friends. Harry and Hermione can always rely on the redhead who grew up with his family at the Burrow! In keeping with his house, he also comes to the fancy-dress party in Gryffindor’s colors of red and gold.

Albus Dumbledore
The headmaster of Hogwarts is considered the greatest wizard of modern times, perhaps even of all time. Dumbledore is distinguished not only by his sharp mind and kind manner, but also by a long robe, a white beard, and half-moon glasses.
Tip
Anyone who wants to stand out at the next Harry Potter–themed party should choose a less well-known costume! How about Fleur Delacour, Dobby, Bellatrix Lestrange, Dolores Umbridge, or the Golden Snitch?
10 decoration ideas for your Harry Potter party
For your party to be a complete success, you need the right decorations. That’s the only way to create a magical atmosphere in your own home. Here are a few ideas for your Harry Potter party:
Let's start with the front door. Hand-painted signs are a great option here. Depending on the theme, choose lettering such as Hogwarts, Chamber of Secrets, Azkaban, Forbidden Forest, Room of Requirement, Great Hall, Shrieking Shack, or Diagon Alley.
Indoors, you can hang the Hogwarts crest and the banners of the four houses: Gryffindor, Hufflepuff, Ravenclaw, and Slytherin.
A large magic cauldron filled with dry ice and water serves as an eye-catching centerpiece for the buffet. This creates a fog effect.
Every wizard and witch needs a wand from Ollivander. Either have several ready for your guests or set up a craft station where everyone can create their own wand.
We all love Harry’s white snowy owl! That’s why no Harry Potter party should be without her. At Kostümpalast, you’ll find a 28 × 13 cm Hedwig decoration.
The Great Hall is a central setting at Hogwarts. The ceiling in particular amazes the new first-year students—let white candles float from your ceiling, too. Or how about flying envelopes from the first film, when Harry tries to catch one?
To decorate the tables to match, choose paper cups and plates as well as napkins featuring a Harry Potter design.
A decorating idea for pranksters: Stick a picture of Moaning Myrtle on the toilet lid. This is sure to scare the occasional guest—perfect for a Harry Potter Halloween party!
Print wanted posters of various Death Eaters or Sirius's wanted poster bearing the text Have you seen this wizard? You can put them on the doors of your home.
Write the following warning on a mirror with red lipstick: The Chamber of Secrets has been opened. Enemies of the heir, beware.
Here comes the serving cart: enchanting snacks and drinks
Another must-have for your Harry Potter party: themed snacks and drinks. After all, your guests should want for nothing! You can also draw inspiration from the story when planning the buffet.

Snacks
- If you’re hosting a Harry Potter birthday party, the cake Hagrid gives Harry for his 11th birthday must not be missing. The chocolate cake with pink icing and green lettering is guaranteed to make every sweet tooth’s eyes light up! And the chocolate theme continues: You can make the legendary Chocolate Frogs using a suitable chocolate mold. Rocher balls can be transformed with paper wings into the walnut-sized Golden Snitch that the Seeker has to catch during Quidditch.
- Bertie Bott’s Every Flavour Beans are among the most popular sweets in the wizarding world. Alongside familiar flavors such as chocolate, peppermint, and blueberry, there are also vomit, earwax, booger, liver, and tripe flavors. The rule here is: every bite is a risk.
- Anyone who wants to serve more than just sweets can offer their party guests savory treats from the world of Harry Potter. How about pumpkin pasties, cocktail sausages, French onion soup, potato casserole, or Yorkshire pudding?

Drinks
- The best-known drink among witches and wizards is probably Butterbeer. It tastes delicious both hot and cold. However, at a Harry Potter children’s party, you should serve this iconic drink without malt beer. Another hit in the wizarding world: pumpkin juice.
- You can easily give your favorite cocktails and soft drinks new names. The various potions leave plenty of room for creativity. Whether it’s the luck potion Felix Felicis, the truth potion Veritaserum, the Polyjuice Potion, or a powerful love potion—the magical mixtures brewed in potion cauldrons can produce a wide variety of effects in those who drink them.
Party game ideas for a Harry Potter-themed children's birthday party
For little witches and wizards, there are many magical games you can prepare for your child’s Harry Potter birthday party. Especially fun: a broomstick race. To do this, set a starting point and a finish line in the garden, and then it’s “Ready, set, fly!” Or organize a spectacular scavenger hunt in which the children have to find Voldemort’s 7 Horcruxes. Another great idea: a Golden Snitch hunt. Hide the golden ball and a treasure chest with small party favors in a secret location. You can fill it with sweets, magic wands, and Hermione’s Time-Turner necklace.
A taste test with Bertie Bott’s Every Flavor Beans is sure to put everyone in a good mood. Blindfold one child with a cloth, and then have them guess the flavors of different beans.
Ready for an unforgettable Harry Potter-themed party?
Whether young or old, the magical world of Harry Potter has secured a firm place in our hearts. To ensure your guests have a wonderful time at your celebration, here are some more ideas for your Harry Potter party.
- Say cheese! With a photo booth and matching props such as ties, wands, the Sorting Hat, Harry's glasses, and balloons, you can take wonderful keepsake photos of yourself and your guests.
- Who knows the Potterverse best? In a quiz with various categories, participants must put their knowledge to the test. Whether spells and potions, Hogwarts, magical animals and creatures, or the Dark Arts—in the end, you crown the biggest Potterhead.
- Flunkyball with a twist: In a Quidditch tournament without brooms, two teams compete against each other. The aim is to finish your drinks faster than the opposing team. Depending on the guests' ages, the game is played with beer or juice.
