Washington Ritter "Rit" Harrison (September 18, 1849 – November 7, 1888) was an American professional baseball player who participated in one game as a catcher and shortstop for the New Haven Elm Citys in 1875.

Requiring a substitute for their May 20 game against the Philadelphia Athletics, the Elm Citys turned to Harrison,[1][2]: 125  a "local amateur".

[3] He began the game at catcher, where he made two errors and gave up two passed balls, and was moved to shortstop, where he made another error.

[1] He married Annabella Shelton in 1877, and they had two children — Theodore and Sarah — and moved to her hometown of Waterbury, Connecticut, where he became employed as a painter, a painter's apprentice and thereafter a brass turner and a foreman, according to the 1870 and 1880 censuses.

Harrison died in Bridgeport, Connecticut in 1888,[3][1] and was buried in Riverside Cemetery in Waterbury.
