Mermaid Birthday Party Invitations

Dive under the sea for a magical mermaid celebration! Our mermaid princess party invitations and matching supplies make it easy to theme your underwater birthday party. You can theme the whole children's birthday party with our invitations, party bags, sweet cone stickers, and thank you cards. Children will adore this cute and colourful artwork, which captures exciting ocean magic.

Choose between ready-to-write and personalised options for your birthday girl's invitations. Ready-to-write postcards are so convenient, as all you need to do is fill in the date, time, and location of the celebration. For that extra personal touch, choose the personalised style and customise with your own wording!

When you personalise an order, we'll email a free proof for you to check. At this point, you can change and amend the text to ensure everything is perfect. We will send it to print once you are totally happy - just approve the proof when you've made all the tweaks you want!

Your child's birthday guests will love these cute accessories, which are printed onto quality materials. And you will love our fast dispatch and free UK delivery on orders over £25! Need your order quickly? Get guaranteed next-day delivery with our Express option at checkout!

What are the most popular party themes?

We have lovely invitations for so many popular party themes. Some of the most popular themes for kids include unicorns, dinosaurs, mermaids, superheroes, swimming, and disco parties! You can choose anything that your child loves for their theme.

How do you pick a party theme?

To pick a party theme, consider what interests the birthday boy or girl! You can base their theme on their favourite animals, TV shows, films, and more. You can check to see if you can find any decorations to match the theme before you settle on your decision.

What activities can you do at a birthday party?

No kids party is complete without party games! We love all of the traditional games, such as Pass the Parcel, Musical Chairs, and Pin the Tail on the Donkey, but feel free to get as creative as you want. A scavenger hunt is also so much fun!

How do you throw the best kids party ever?

There’s so many ways that you can make a party fun! We recommend having delicious food and drinks, fun party games, exciting decorations, and party favours for all of the guests. You could also hire a performer to make the party even more memorable.
