"Fins" is a song recorded by American popular music singer-songwriter Jimmy Buffett.

It was written by Buffett, Coral Reefer Band members Deborah McColl and Barry Chance, and author Tom Corcoran.

Cash Box said that "swinging southern pop-rock, served up Florida style, compliments the neat double entendre.

Buffett usually began the song with a few bars of the "Main Title" theme from the movie Jaws.

In 2009, Buffett wrote new lyrics to the song for the Miami Dolphins football team.
