Best Answer

It's probably George. It was established in an NCIS LA episode that his grandfather's name was George, and it's common for people to name their kids after their parents. So it's very possible that Callen's first name is George.

His legal name is G. Callen. He does not know his true first name because no one has ever told him. This is because his parents left him when he was a kid and all he ever found out was it started with a G. So thus his name is G. Callen.
