Joshua Mercer Goar (January 31, 1870 – April 4, 1947), was an American professional baseball player who was a pitcher in the National League in 1896 and 1898.

Listed at 5 feet 9 inches (1.75 m) and 160 pounds (73 kg), he threw and batted right-handed.

[1] Minor league records, incomplete for the era, list Goar as playing in the Western League during 1895–1897, and for the Indianapolis Hoosiers in 1900.

[3] Goar is noted for an unusual inning pitched when playing for the minor-league Anderson Tigers in the Indiana State League.

[4] The unusual sequence of events included two runners being tagged out at the plate, and the final out coming when a batted ball hit a baserunner (which officially credits the batter with a hit).
