Alan Robert Hargesheimer (born November 21, 1954) is an American former Major League Baseball pitcher.

Since his retirement, Hargesheimer has worked as a scout for several teams, including the Detroit Tigers, Colorado Rockies and San Diego Padres.

[1] Signed by the San Francisco Giants in 1978 as an amateur free agent, Hargesheimer made an impressive Major League debut on July 14, 1980.

He was the starting and winning pitcher in a 5-3 victory over the host Cincinnati Reds at Riverfront Stadium, supported by a first-inning Jack Clark home run and by his own run-scoring double in the fourth.

After his trade to the Kansas City Royals in 1984, injuries limited him to only 5 games in 1986 after which he retired in December of 1988 to pursue a scouting career.
