William Ross Fiscus (April 2, 1870 – November 6, 1950) was an early professional American football player and coach.

Fiscus played for the Allegheny Athletic Association professional football team as a lineman in 1891 and 1892, but by 1893 he had successfully earned the role as halfback.

[2] This would have put him alongside the first recorded professional football player Pudge Heffelfinger, who also played for Allegheny.

Fiscus was the second head football coach at Geneva College in Beaver Falls, Pennsylvania, and he held that position for three seasons, from 1897 until 1899.

[3] Fiscus died November 6, 1950, at his home in the Mount Washington neighborhood of Pittsburgh, Pennsylvania.
