Brian Lee Simmons (born September 4, 1973) is an American former Major League Baseball (MLB) outfielder.

He played for the Chicago White Sox and Toronto Blue Jays over parts of three seasons.

Simmons would make his Major League Baseball debut with the Chicago White Sox on September 21, 1998, and appeared in his final game on October 7, 2001.

On September 26, 1998 against the Royals, Simmons hit home runs from both sides of the plate, establishing a new record for fewest at-bats required to do so.

[citation needed] His fledgling career was derailed, however, when he ruptured his Achilles tendon late in 2000 spring training.
