Al Rinker (December 20, 1907 – June 11, 1982) was an American musician who began his career as a teen performing with Bing Crosby in the early 1920s in Spokane, Washington.

In 1925 the pair moved to Los Angeles, eventually forming the Rhythm Boys trio with Harry Barris.

Rinker was born in Tekoa, Washington; his mother, Josephine, was an enrolled member of the Coeur d'Alene Tribe[1] and a devout Roman Catholic.

The Rhythm Boys were filmed for the movie King of Jazz (1930) singing "Mississippi Mud", "So the Bluebirds and the Blackbirds Got Together", "A Bench in the Park", and "Happy Feet".

In 1952, a song for which Rinker wrote the music with lyrics by Floyd Huddleston, "You Can't Do Wrong Doin' Right", appeared in the films Push-Button Kitty and The Affairs of Dobie Gillis.
