Home Run Records in a Single Season

Major League Baseball Single Season Home Run Records

Baseball Almanac is pleased to present a record book full of baseball milestones for home runs hit during a single season — including most, most by positions, most at home and most on the road.

IMPORTANT NOTE: Many totals do not match-up exactly with single season totals when positional records are viewed. This is because the home run MUST be hit while the player is at that position. Example: Mark McGwire finished the 1998 season with seventy home runs. However, one of his home runs was hit while he was pinch-hitting so his single season record for home runs by a first baseman is sixty-nine.
