Actor Rex Harrison is a famous bearer of the name. It's also a very popular name for dogs for many decades which has spoiled this beautiful name for me. There's a German TV series named "Komissar Rex" about a German Shepherd Dog.
Despite the negative reception of this name on the 'ratings,' I think this is one of the best names for a boy. It's simple and understated, yet still has a strong meaning and originality.
In the movie Napoleon Dynamite, there's a martial arts teacher named Rex. He is the inventor of "Rex-Kwon-Do." Ha ha. I wouldn't name my son Rex for this reason alone.

The quarterback for the Chicago Bears is named Rex Grossman.
I disagree that Rex is suitable only for a dog. I think it's a very handsome name, and any boy would be lucky to receive the name Rex rather than Joshua, Justin, Michael, or Jacob, which are nice names but way overused.
I simply don't like this name for a person. For a dog maybe, but not for someone. Makes me think of tyrannosaurus rex.

I like it, Rex always reminds me of Mardi Gras, since Rex is considered "The King of Carnival".

I have a cousin named Rex. He is sometimes called 'T' as in the dinosaur Tyrannosaurus Rex. I would personally never name a child Rex. It sounds more like a nickname or a name for a pet. Being called 'Dino' or 'T Rex' might get old, so consider thinking twice before naming a child this.
Rex is my name and I wouldn't trade it for nothing. Call it a dog's name or whatever you may, nonetheless it is one that is uncommon and unique making it very hard to forget. The name Rex itself has been a social aid since kindergarden to this day. And only recently in the last of my high school years has this dawned on me. Long Live the Rexx.
Angelina Jolie and Brad Pitt had planned to name the boy twin Rex but changed it to Knox, which may be a reference to Archibald Knox or Pitt's late grandfather.

Rex Bell, the western actor. He was married to Clara Bow.
Somebody with this name would get rhyming jokes about sex.

I can't believe this is ranked #705 in the US... Did they get this one mixed up with popular dogs names or something?!

This is my name and i like it a lot. I'd say about the only downside for me is that people are constantly accidently calling my dog Rex, and half the time they don't even realize it. His name is Sarge so it's not even very close. Just a reaction since Rex is associated with a canine's name these days, i suppose.
