Kevin Christian Maas (born January 20, 1965) is an American former Major League Baseball player.

He started his big league career on a tear, setting a record for the fewest at bats (72) to hit 10 home runs (since broken by Shane Spencer in 1998).

At the end of the 1990 season, Maas had hit 21 home runs in 79 games and he finished second in The Sporting News Rookie of the Year Award voting to Sandy Alomar Jr. of the Cleveland Indians.

About halfway through the season a group of a dozen or so young ladies began wearing "Maas-tops" to the Yankees home games and sitting in the right field stands.

Maas then signed with the Hanshin Tigers of Japan's Central League in 1996 to replace Glenn Davis.
