Walter Scott Bowman (February 8, 1865 – November 27, 1938) was a prominent professional photographer in Pendleton, Oregon. His work is included in the University of Oregon's Bowman, Moorhouse, Furlong, and Drake collections. Bowman captured well known action shots from the Pendleton Round-Up that are included at the National Cowgirl Hall of Fame. The National Cowboy Museum includes numerous Bowman photographs and postcard images. Bowman photographed events around Umatilla, Oregon including parades, marching bands, railroad scenes, Pendleton High School team pictures, dances, studio portraits and images of Native American (the Umatilla Indian Reservation is adjacent to the city of Pendleton). The University of Oregon's Walter S. Bowman photographs collection includes 379 glass-plate negatives, 51 cellulose acetate negatives, and 200 silver gelatin photoprints.
Bowman was part of a prominent pioneer family that came west from Iowa in 1862. His parents were married in Osceola, Iowa. His cousin, Oliver Purl Bowman (1862-1939), built the Bowman Hotel (Pendleton, Oregon).
