William Ambrose Hulbert (October 23, 1832 – April 10, 1882) was one of the founders of the National League, recognized as baseball's first major league, and was also the president of the Chicago White Stockings franchise.

Born in Burlington Flats, New York, Hulbert moved with his family to Chicago two years later where he lived the rest of his life save for a stint at Beloit College beginning in 1847. When he returned to Chicago from school, he married into the family of a successful grocer and expanded the business into the coal trade. A backer of the Chicago White Stockings baseball club of the National Association from its inception in 1871, Hulbert became an officer of the club in 1874 when it resumed play after being forced to sit out two seasons due to the Great Chicago Fire and assumed the presidency the next year.

In his brief tenure as a club president in the National Association, Hulbert soon became fed up with the circuit's lack of definite structure, organization, and integrity. He was particularly disgusted by the Davy Force case in 1874. Force, the shortstop of the White Stockings that year, was a notorious "contract jumper", a common occurrence in the National Association in which players would move from team to team each year selling themselves to the highest bidder. Determined to keep his shortstop, Hulbert signed him to a contract for the 1875 season in September, before the 1874 season had concluded, a violation of league rules. In December, Force signed a second contract with the Philadelphia Athletics, and Hulbert protested. The Association Judiciary committee originally awarded Force to Chicago, but at a second meeting in early 1875, after a Philadelphia man had been elected president of the association, the decision was reversed.
