Edward Nagle "Ned" Williamson (October 24, 1857 – March 3, 1894) was a professional baseball infielder in Major League Baseball. He played for three teams: the Indianapolis Blues of the National League (NL) for one season, the Chicago White Stockings (NL) for 11 seasons, and the Chicago Pirates of the Players' League for one season. His career was shortened by a knee injury that he suffered in Paris during a world-tour organized by Albert Spalding. After he left organized baseball, his health declined rapidly. He contracted tuberculosis and ultimately died at the age of 36 of dropsy.
