William Otis "Otey" Clark (May 22, 1915 – October 20, 2010) was a Major League Baseball pitcher who played for the Boston Red Sox in 1945.

His finest pitching effort that season came on September 19 in the second game of a doubleheader at Fenway Park.

Also good with the bat and glove, Clark hit .208 (5-for-24) and handled 11 chances in the field without an error.

One day before appearing in the 1945 season opener, Clark pitched to Jackie Robinson in the latter's tryout for the Boston Red Sox.
