MLB on Fox (also known as Fox MLB) is an American presentation of Major League Baseball (MLB) games produced by Fox Sports, the sports division of the Fox Broadcasting Company (Fox), since June 1, 1996. The broadcaster has aired the World Series in 1996, 1998, and every edition since 2000, and the All-Star Game in 1997, 1999, and every year since 2001. It has also aired the National League Championship Series (NLCS) and American League Championship Series (ALCS) in alternate years from 1996 to 2000 and since 2007, with the NLCS in even years and the ALCS in odd years (the network aired both series from 2001 to 2006).

In 2022, Fox Sports renewed its television rights for regular season games for both the main Fox broadcast network and FS1 through 2028. Per the contract, Fox airs regular-season MLB games each Saturday. Fox continues to exclusively broadcast the World Series, All-Star Game, and Field of Dreams Game for the life of the contract.
