Timothy Joseph Spehr (born July 2, 1966) is an American former professional baseball player.

He played in Major League Baseball as a catcher for the Kansas City Royals (1991, 1997 and 1998–99), Montreal Expos (1993–96), Atlanta Braves (1997) and New York Mets (1998).

In his first at-bat with the Atlanta Braves in 1997, he hit a grand slam (the first of two in the game, the second by Ryan Klesko) to help power a comeback from a 6–0 deficit to the Phillies.

Spehr's best season was his last, where he set career highs in many offensive categories.
