Frist off, welcome to TCS! I hope you'll stick around our friendly community. Second, what a beautiful cat! But my guess would be no. Could be a Bombay mix, but looks like a DSH like my Bree. I think the white patches on their necks are called something, like an angel's kiss. (Bree is a pretty girl, but she doesn't photograph well.)
Bombay cats have a very specific look: round head, rounded ears, wide-set round eyes that are gold or copper, no white spots allowed. I don't see any of that in your cat. Without a known history/pedigree your kitty is considered a Domestic Shorthair, no specific breed.
Lovely black cat. What is his or her name?
