William F. Etter (born February 18, 1950) is a former American football quarterback. He was an All-American at Lewis & Clark High School in Spokane; a two-game starter for the University of Notre Dame until a knee injury ended his college career; and a three-year backup for the CFL's Hamilton Tiger-Cats, from 1973-1975. He is currently a commercial and personal injury defense lawyer in Spokane.
Etter held the Notre Dame record for the most rushing yards by a quarterback in a single game—146 yards against the Naval Academy, accomplished as a backup to Joe Theismann in 1969.
