Dustin Michael Hermanson (born December 21, 1972) is an American former right-handed pitcher in Major League Baseball (MLB).

He had his best season with the 2005 Chicago White Sox team that won the World Series; he had 34 saves that year before sustaining a season-ending back injury in September.

With Montreal and St. Louis, Hermanson was mostly a starting pitcher, while he moved mostly into a relief role with the latter three teams.

[1] It was also during his first season with Montreal that he had his first ever at-bat, hitting a home run off Shane Reynolds in the fifth inning,[3] one of only a handful of pitchers to achieve this feat.

He served as the closer for the White Sox during most of their 2005 championship season, saving 34 games before being replaced by rookie Bobby Jenks in late September when he injured his back.
