Cousins are the weird in-between — not quite sibling, not quite friend, but somehow the person who remembers exactly what your gran's lounge smelled like in 1998. Maybe yours grew up two streets over in Joburg and your families did every Easter together. Maybe yours is the cousin from the Cape Town side you only see at funerals and Christmas. Either way, when their birthday lands in the family WhatsApp group, a one-line 'HBD cuz!' doesn't quite cover it. Below are original birthday wishes for every kind of cousin — copy, tweak the name, and send.

Heart-Touching Birthday Wishes for Your Cousin (Brother)
For the cousin who's been a brother in everything but the surname.
- Happy birthday to the cousin who's been more of a brother than most brothers I know. Half my best stories start with your name in them, and I wouldn't have it any other way.
- You're family by blood and brother by choice, which is the rare double a person doesn't get often in one lifetime. Wishing you a year that gives back even a fraction of what you give the rest of us.
- Every family has one cousin who shows up when it actually matters. You're ours. Happy birthday — may this year be kinder to you than you've been to everyone else.
- The thing about you is that the older we get, the less the 'cousin' bit matters and the more the 'brother' bit does. Happy birthday, my guy.
- Happy birthday to the cousin who knew me before I figured out how to hide anything. There's a comfort in being known like that. Thanks for never using it against me.
Sweet Birthday Wishes for Your Cousin (Sister)
For the cousin who's basically a second sister — the one your mum still calls 'my other daughter'.
- Happy birthday to my cousin, my partner-in-crime since the playpen days. Growing up with you nearby has been one of the soft, lucky things about my life.
- You've been my cousin, my sounding board, my second wardrobe, and my emergency contact in roughly that order. Wishing you a birthday as good as you've been to me.
- Some friendships you build. Ours came pre-installed. Happy birthday to the cousin who's been the easiest person in my life to love.
- To my favourite cousin — yes, of all of them. Happy birthday. May this year hand you everything you've quietly been working towards.
- Happy birthday, cuz. If our gran could see us now she'd be smug about how close we still are. She always said we'd turn out fine. Turns out she was right.
Funny Birthday Wishes for Your Cousin
For the cousin who'd rather you roast them than send something soppy.

- Some people are born sisters and some sisters are made over a thousand sleepovers, a few terrible road trips, and one shared bottle of cane and creme soda. Happy birthday, sis-cousin.
- You're the cousin I'd pick out of a line-up of sisters every time. Wishing you a year that finally lets you breathe.
