Thomas Joseph Davey (born September 11, 1973) is an American former professional baseball pitcher.

At 6'7", Davey was a right-handed relief pitcher for three years with the Toronto Blue Jays (1999), Seattle Mariners (1999), and San Diego Padres (2000–2002).

In December 1996, the Baltimore Orioles claimed Davey in the minor league draft, but returned him to the Blue Jays three months later due to his lackluster performance overall.

In 11 games for the Padres in 2000, Davey had a 2–1 record with 6.48 earned run average (Adjusted ERA+ of 600) in 12-2/3 innings.

Davey underwent a fourth shoulder surgery in early 2010, and while he hoped to attempt another comeback, the repair did not heal well enough to allow him to continue pitching.
