Writing fun birthday captions for your social media posts can take ages to get right. Maybe it’s trying to strike a specific tone – thoughtful, funny, sentimental or sweet. Or finding the perfect words for your birthday boy or girl. Or working out a happy birthday caption for yourself on your own birthday. It can feel like the words are out of reach. But lucky for you, in this article, I’m going to share some of the most thoughtful, humorous, and fun birthday caption ideas. Whether the birthday caption is for yourself, a boyfriend or girlfriend, a family member or a best friend.

All that’s left to do will be choosing a photo and selecting the perfect Instagram filter. And getting them a birthday card, of course!

It’s your birthday! The perfect time to write a reflective story or share the best moment of your day so far!

Your birthday caption for yourself can be about anything; any goal, any message. You could even leave yourself a letter of appreciation—the options are limitless. 

But, if you’re short of words, I have curated some great captions to write for yourself.

#2 Reflecting

Birthdays are a time for reflection, for looking back on the past year, and for setting your sights on the year ahead. This birthday marks the start of a new journey around the sun for me with all of my lovely and supportive friends, and I couldn’t be happier. Thank you for being a part of my life in the past year, for being there for me, and for always making me smile! I can’t wait to celebrate with you all!

#3 Do what makes you happy

Dear me, please do what makes you happy this year! Never settle for less than what you deserve. Happy birthday!

Best friends are life, aren’t they? They laugh with you, cry with you, cherish your wins, and mourn the losses. 

So, on their special day, you should do something really creative for them to put a beautiful smile on their face. Maybe, share a beautiful collage video with memories or an until-now unseen picture of you two chilling together? 

Whatever you share, what to write in the caption is certainly not the question! Here are some caption ideas you can take inspiration from.

On your birthday, take a moment to think about your dreams and what you want to achieve in the coming year. Because you can do anything! Wishing you all the best on this special day and in the year ahead.

#20 Someone loves you more than…

Hey, on your birthday, I just wanted to remind you; someone loves you more than you love your cats (me)! So be nice and show up for dinner tonight.

Tip: Replace ‘cats’, with their favorite topic. E.g. make up, girls, football, etc.

#21 I love you… a bit.

Happy birthday, bro / sis! Don’t mistake my birthday wishes for love. Deep inside; I still hope you go to JAIL for all the mean things you said to me when we were kids. (Okay, FINE, I love you a bit.)

Good luck with your post!


Hiya, I’m Maud. I’m an English girl who's moved to Berlin - because who wouldn’t fall in love with a country which has words like ‘Kummerspeck’ hidden around every corner... I love traveling and finding out the quirks of each country - and what better way to remember them than on a postcard?
