William Sherman Jennings (March 24, 1863 – February 27, 1920) was an American politician who served as the 18th governor of Florida after being a lawyer, county judge, and state representative.

He finished his law studies in Chicago under the supervision of his brother, Charles E. Jennings, who was the State Attorney for Marion County.

After his term ended, he served as a colonel in the Florida militia, was president of the Brooksville town council and chairman of the Democratic committee.

[3] In 1905, he was appointed by Governor Napoleon B. Broward as general counsel for the Internal Improvement Fund, the state agency responsible for administering public lands.

In addition to his brother, who was a lawyer and state attorney, he was a first cousin to William Jennings Bryan, congressman and three-time Democratic presidential nominee.

At one point, the controversy became so heated that Jennings and Lincoln Hulley, the president of the university, engaged in a fistfight in the lobby of the Leon Hotel in Tallahassee, Florida.
