Happy 15th Birthday Wishes for 15 Year Olds

The 15th birthday of a teenager is never easy. They’re known for being surly and moody, and definitely not wanting to celebrate with their family.

So trying to wish someone a happy 15th birthday and show you care is tough. Finding words that will get through to a teenager and actually resonate with them isn’t easy.

If you can’t get a 15 year old to look up from their phone any other time what chance have you got even for their birthday?

Hopefully then these 15th birthday wishes will help.

If you are struggling with a birthday card message for a 15 year old these funny and heartfelt quotes and wishes are perfect.

Try using them in a card, saying in person or the teenagers preferred method of communication – Instagram/Facebook/TikTok!
