Leo Edgar Hafford (September 17, 1883 – October 1, 1911) was a professional baseball player who played pitcher in the major leagues. He attended Tufts University. He also attended Bowdoin College, and went on to coach football at the University of Connecticut in 1911. He served as head coach only briefly, however, as he died from typhoid fever three weeks after accepting the position. He ended up only coaching one game, but was credited as head coach for the whole season.
