Walter Dedaker Shaner (May 24, 1900 – November 13, 1992) was an American reserve outfielder in Major League Baseball, playing mainly at left field for three different teams between the 1923 and 1929 seasons.

A native of Lynchburg, Virginia, Shaner spent 13 years in baseball (1920–1932), including parts of four major league seasons with the Cleveland Indians (1923), Boston Red Sox (1926–1927) and Cincinnati Reds (1929).

His most productive season came in 1927 for the Red Sox, when he had a .273 batting average in a career-high 122 games.

While playing for the 1925 Lincoln Links of the Western League, Shaner finished fourth in the batting race with a .358 average in 122 games, while collecting 230 hits, 85 RBI, 145 runs and 85 extrabases.

Following his baseball retirement, Shaner worked as a stage manager at the Stardust Hotel in Las Vegas, Nevada.
