Anthony John Mullane (January 30, 1859 – April 25, 1944), nicknamed "Count" and "the Apollo of the Box", was an Irish professional baseball player who pitched for seven major-league teams during 1881–1894.

He made his major league debut with the Detroit Wolverines on August 27, 1881, picking up his first career win 9–1 over the Chicago White Stockings.

In 1882, Mullane moved on to the American Association and joined the Louisville Eclipse, where he started 55 of the team's 80 games and compiled a record of 30–24 with a 1.88 earned run average, the first of five consecutive 30-win seasons.

In 1884, Mullane attempted to sign with the St. Louis Maroons of the Union Association, a new independent league, even though under the reserve clause the Browns still had rights to his services.

That season, Mullane was teamed up with catcher Moses Fleetwood Walker, one of the first black men to play in Major League Baseball.

His 284 wins tie him with Ferguson Jenkins for 27th on the all-time list; he is fourth among eligible pitchers not in the Hall of Fame, behind only Roger Clemens (354), Bobby Mathews (297) and Tommy John (288).
