Scott David Schoeneweis (born October 2, 1973 Long Branch, New Jersey) is an American left-handed relief pitcher in Major League Baseball for the Arizona Diamondbacks. He was briefly placed on the restricted list in May 2009 following his wife's sudden unexpected death, but returned to the mound on June 13th.

In the five seasons from 2003-2007, Schoeneweis allowed only one home run to a left-handed batter. Left-handed hitters batted .209, with a .264 slugging percentage and .293 on base percentage, in 227 plate appearances against him from 2005-2006, and then only .207 with a .241 slugging percentage in 2007. In 2008, he was even stingier -- lefties batted only .178 against him. That was second-best among all major league lefthanders.

Schoenweiss grew up in Mount Laurel Township, New Jersey. He attended Lenape High School in Medford, New Jersey, where he lettered in baseball and basketball before playing collegiately at Duke University, where he was a 1993 All-American as a freshman. That season, he had 12 wins, the second best record in the school's history.
