Jack or Caspian

We can't choose! I've always loved Jack, and it feels a safer choice, but is it still so common? I love the nickname Cass, but is Caspian too pretentious? All thoughts welcome!

Jack is THE most boring name!!!

Caspian, Jack is so dull and unimaginative.

Casspian

Chose Caspian because I would never use Jack, but if you're struggling between two names, neither of them is the one, OP...

I voted Caspian of the two, but I much prefer Cassian, or even Caspar.

Jaspian... Cassack... Caspiack?

JillyGiraffe · 20/06/2025 20:36

I vote Jack! I don’t know of any little ones with the name. My children both have popular names but that doesn’t bother me. Caspian seems more pretentious than Caspar. Not sure if children these days will know about Caspar the friendly ghost, but I think it’s a lovely name!

Caspian caspian caspian please please please use it

TaupeMember · 20/06/2025 19:58

Love jack.

Moreteaandchocolate · 20/06/2025 19:48

Definitely Jack for me. Caspian is a bit frilly / pretentious and I don’t like Cass for a boy - to me that’s short for Cassie / Cassandra.

Caspian 100% - great name!

BoleynMemories13 · 20/06/2025 19:21

100% Jack

A timeless classic, and there are nowhere near as many little ones about these days.

I really dislike Caspian and the nn Cass for a boy. Casper is slightly preferable (far less pretentious) but I still much prefer Jack.

We loved Caspian for our son before he was born. I'll be honest, I'm glad we didn't call him that in the end!

Prefer Caspar nickname Cass

SeaDragon17 · 20/06/2025 18:55

Cass sounds very effeminate. Jack is too common (and is also a nn and I have a personal dislike of nn being given rather than the actual name, but I know I am in the minority there).

In short - do you have any other names you like? What about Jasper (nn Jas) or Sebastian?

theotherfossilsister · 20/06/2025 18:51

How about Jolyon (could be Jem but has the three syllables of Caspian and same feel)

Temporaryname158 · 20/06/2025 18:50

Jack, timeless. Caspian, pretentious and nobody will ever call him that so why not just call him Cass in the first place

yestothat · 20/06/2025 18:49

Caspian nickname Cass.
Jack is far to boring

WaltzingWaters · 20/06/2025 18:47

Caspian. Jack is overused.

GoldenRosebee · 20/06/2025 18:46

Caspian, no question. Jack is overused.
