100+ Birthday Wishes for Your Cousin Sister To Make Her Special Day Sweeter


For a cousin and a sister all rolled into one
I’m wishing you a birthday that’s full of fun!

Happy birthday, my dear! 

Here’s to the many years of laughter and 
creating wonderful memories together 
that are still waiting to be written!
It’s no wonder people mistake us for
siblings rather than cousins because I too
sometimes forget that you are my cousin
as you’re so much more like a sister to me!

Happy birthday, my dear! I hope your
special day is as special as you are to me!
I wanted to get something extraordinary 
and particularly special for a cousin 
who is more like a sister to me, 
but then I realized something:
You already have all of that in me!

I hope your birthday is as wonderful and 
as meaningful as you are to me, my dear! 
Wishing a very happy birthday to you!
Don’t worry about getting older, my
dear cousin!

It happens to us all but luckily for us,
we have great genes that should see
us age more gracefully than others!
How fortunate are we!

I hope you have a birthday that’s as
beautiful and fabulous as you are!
A cousin on paper
A sister at heart
I could never cope
If we were ever apart!

Wishing you the happiest
Birthday possible, my dear!
Happy birthday, my dear cousin! Congratulations on still maintaining your youthful looks despite the many, many, many years that are against you!
We must be related because you have so
much style and sophistication just like me!

If people didn’t know any better or that
we’re cousins, they would definitely think
that we’re sisters!

Happy birthday, my dear! I hope you enjoy
your special day today!
My dearest cousin, you are
the sister I was never lucky
enough to have and I wish
you only beautiful things
on your very special day!

Happy birthday!
Happy birthday to you!

If I had to give just one reason why you’re more like a sister to me than a cousin, it would be that growing up together you would annoy me just as much as any sister would!
Happy birthday to you, my sweet cousin!

Seeing as it’s your special day, I’ll let you in on a little secret: I know your true age! Well, with us being as close as we are what else would you expect!
If I didn’t know any better I’d never guess it was your birthday today as you don’t look a day older, let alone a year! Happy birthday, my beautiful cousin!
Happy birthday to my beautiful cousin, who will always be more like a sister to me!
Wow, another birthday already, cousin?
With all these years behind you now,
perhaps you’ll finally start to grow up soon!

I’m just kidding with you! I wouldn’t change
your fun and playful personality for the
world! Happy birthday to you!
Happy birthday to my cousin who
funnily enough happens to have
the best cousin in the world!

How crazy is that!
Growing up together we were inseparable,
and even now years later it is no different!

We are closer than cousins, we are soul
sisters for sure! I hope that you have the
most incredible birthday today that you
deserve, my dear!

You mean so much to me and I just want
to see you happy in life!

A very happy birthday to you, sweetie!
