Bill O'Hara (baseball)

William "Bill" O'Hara (born circa 1868, date of death unknown) was an American professional baseball player. He played primarily as a catcher and outfielder in Major League Baseball (MLB) from 1890 to 1894.

O'Hara's MLB career began with the Philadelphia Athletics of the American Association in 1890. He played for the Athletics for part of that season before joining the Pittsburgh Alleghenys of the National League for the remainder.

In 1891, O'Hara played for the Philadelphia Athletics (this time in the American Association again). He split the 1892 season between the Washington Statesmen/Senators and the Baltimore Orioles, both of the National League.

His final season in MLB was 1894, with the Baltimore Orioles. After his major league career, he continued to play in the minor leagues for some time. Further details about his minor league career and life beyond baseball are scarce.
