William Edward "Wid" Conroy (April 5, 1877 – December 6, 1959) was an American Major League Baseball player active during the first decade of the 20th century.

(72 kg), Conroy epitomized the role of a utility man, playing every infield and outfield position in his 11-season career.

Conroy began his career as a shortstop, replacing Honus Wagner with Paterson in the Atlantic League, but was struck by malarial fever and dropped from the team.

In 1900 Connie Mack invited him to try out for the Western Association team he would field in Milwaukee and transfer to Philadelphia when the American League began as a major circuit; Conroy won the last spot on the roster.

Conroy was the first-string shortstop of the NL champion 1902 Pirates but became a third baseman when he returned to the AL with the Highlanders (later the Yankees) in 1903.
