Walter J. Weber (born c. 1905) was an American football player and coach at the University of Michigan. He played halfback and fullback for the Wolverines in 1925 and 1926 on the same teams as Benny Friedman and Bennie Oosterbaan. He later became an assistant football coach at Michigan for 28 years from 1931 to 1958. He continued to work for the University of Michigan in recruiting and alumni relations and as an instructor of physical education until his retirement in 1972. He also provided color commentary on WPAG radio's broadcasts of Michigan football games with Bob Ufer. From 1927 to 1930, he was football coach at Benton Harbor High School, leading the Tigers to the state championship in 1929. He was inducted into the University of Michigan Athletic Hall of Honor in 1981 as part of the fourth group of inductees. Only seven football players were inducted into the Hall of Honor before Weber.

A native of Mount Clemens, Michigan, Weber played football at Michigan in 1925 and 1926 as a halfback and fullback in the same backfield with College and Pro Football Hall of Famer Benny Friedman and College Hall of Famer Bennie Oosterbaan. In 1927, Weber scored two touchdowns against Wisconsin in Fielding H. Yost's last game as Michigan's football coach (also the last Michigan football game played at Ferry Field). Michigan won the game, 37–0. The next week, Michigan played Ohio State in Columbus, and an anxious Weber was quoted as saying to Oosterbaan, "Ben, at this rate they're going to beat us 40-0." Oosterbaan reportedly replied, "Dammit, Wally, we haven't had the ball yet."
