William Henry McClellan (March 22, 1856 – July 3, 1929) was an American Major League Baseball player for eight seasons, and primarily played as a second baseman and shortstop from 1878 to 1888.

Born in Chicago, McClellan played one season for the St. Paul Red Caps of the League Alliance in 1877.

Brooklyn captain Dave Foutz ordered his team off the field in protest, and the game was ruled a forfeit in favor of Kansas City.

[1] Despite the fact that McClelland had come off a good season in 1887, Brooklyn benched McClellan midway through 1888 and gave his starting position to Jack Burdock, a 36-year-old player who had just been released by Boston for intemperance.

Toward the end of the 1888 season, Brooklyn sold McClellan to the Cleveland Blues, and he finished his major league career there that year.
