It's OK for a girls name, but it sounds a little hippy (in the "flower-power" sense). Generally, English names do have meanings, but they don't function as nouns. That's why it sounds a little unusual. Interestingly, the word comes from Greek, and in Greek mythology Ocean was always represented as a male. Still, it's fine for a name (male or female) if you're happy with it.

I went to the Phillppines to study abroad and I was given an English name. My teacher choose it for me but you know, I am a girl. Is it a female name? and I want to know what it means. Answer. It is not a traditional English name. It could be an female name, but you would say that it would be regarded as a unisex name - neither male nor female. From her choice of name, I think that your teacher is something of a bohemian. The name itself would not be regarded as offensive and you might find that a number of English speakers will ask you how you acquired the name.

well there are a lot opinions that the name is fun. Okay good!^^ I satisfied this name because it sounds cool doesn't it? haha My actual personality is really like boy so..i like it:-) And it is not normal name, it means somewhat special and i get to be a curious girl doesnt it?? GOOD. From now, call me "Ocean"

- It's not a tradition to have an English name with a meaning. Ocean is good but normal people would find your name funny. But if you like it, go for it. Haha, lol. XD
