William A. Walsh (August 18, 1871 – March 18, 1967) was an American football player for the University of Notre Dame, an attorney, and a mayor and city judge of Yonkers, New York.
During his senior year in 1895, Walsh played under head coach H. G. Hadden.
His starts included shutout victories over Northwestern and Chicago Medical, but the team suffered a controversial defeat at the hands of Indianapolis Artillery, who featured Winchester Osgood at halfback, despite questions surrounding the former All-American's eligibility.
As a Democrat in 1917, he was appointed City Judge of Yonkers, New York, but lost his reelection bid to future gubernatorial candidate William F. Bleakley.
