Gavin Christopher Floyd (born January 27, 1983, in Severna Park, Maryland) is a Major League Baseball starting pitcher for the Chicago White Sox. He stands 6'5" tall, weighs 220 pounds, and throws and bats right-handed.

In 2001, Floyd was selected fourth by the Phillies in the MLB amateur draft, just ahead of fellow Mount Saint Joseph High School graduate and New York Yankees All-Star Mark Teixeira.

In his first professional season (2002), Floyd pitched for the Class A Lakewood BlueClaws of the South Atlantic League. A highlight of his impressive first year (2.77 ERA, .200 BAA) was pitching the first nine-inning no-hitter in BlueClaws history on July 24 against the Lexington Legends. However, Floyd actually lost the game, 1-0, due to a pair of sixth-inning errors, making him the first SAL pitcher since 1966 to lose a no-hitter.
