William Henry "Harry" Wright (January 10, 1835 – October 3, 1895) was an American professional baseball player, manager, and developer. He assembled, managed, and played center field for baseball's first fully professional team, the 1869 Cincinnati Red Stockings. He is credited with introducing innovations such as backing up infield plays from the outfield and shifting defensive alignments based on hitters' tendencies. For his contributions as a manager and developer of the game, he was inducted into the Baseball Hall of Fame in 1953 by the Veterans Committee.
Wright was the first to make baseball into a business by paying his players up to seven times the pay of the average working man. He is the oldest former professional player in the Hall: a few other inductees were born before him, but none of them played professionally. His younger brother George Wright is also in the Hall.
