Arthur Richard Dede (July 12, 1895 – September 6, 1971) was a professional baseball player who played catcher in one game for the 1916 Brooklyn Robins. Dede was a local Brooklynite semi-pro catcher who had been traveling with the team to catch batting practice. He got into the only Major League game of his career when third-string Brooklyn catcher Mack Wheat broke a finger in the sixth inning of the season's penultimate game. He caught the final three innings with Leon Cadore pitching.
After his playing career ended, he was a scout for the Brooklyn Dodgers from 1947 to 1957 and the New York Yankees from 1958 to 1971.
