Ned Williamson (October 24, 1857 - March 3, 1894) was a Major League Baseball player for the Indianapolis Blues (1878), Chicago White Stockings (1879-1889), and Chicago Pirates (1890).
He was born in Philadelphia, Pennsylvania. In 1884, Williamson set the single season home run record with 27 in a 112-game season, besting the record of 14 set by Harry Stovey the previous year. Historians look upon that record skeptically, due to the all-too-friendly dimensions of Chicago's Lakeshore Park.
Williamson died at age 36 in Willow Springs, Arkansas.
