Morris Medlock "Buddy" Hancken (August 30, 1914 – February 15, 2007) was an American catcher in Major League Baseball who played during the 1940 season.

Then reached the Majors when manager Connie Mack knew he could catch knuckleballs and wanted him as the fourth catcher for the Philadelphia Athletics.

From 1942 to 1946 Hancken served in the United States Marines during World War II, but he would not leave baseball behind forever.

He managed ten different minor league teams, spent time as a scout for several clubs, and served as a bench coach for the Houston Astros from 1968 through 1972.

He then joined the Astros front office staff in 1971 and 1991–92, being recognized as a mentor to players like Enos Cabell, Larry Dierker and Art Howe.
