William J. Gibson (died September 9, 1863) was an American physician, politician, and Wisconsin pioneer. He was a member of the Wisconsin Senate (1855 & 1856) and State Assembly (1854) representing a large swathe of the then-lightly populated northwest Wisconsin. He was one of dozens of lawmakers in the 1856 session caught up in the La Crosse and Milwaukee Railroad bribery scheme. He died of disease while serving as a Union Army officer in the American Civil War. Biography William J. Gibson came to Wisconsin some time before 1852. He first resided in Rock County, Wisconsin, but soon moved to Jackson County, Wisconsin. He was a candidate for the Democratic nomination for Wisconsin Senate in 1852, but did not receive the nomination. The next year, however, he received the Democratic nomination for Wisconsin State Assembly in his district and won election in the fall. At the time, his district comprised a wide swathe of western Wisconsin, encompassing all the territory from the northern border of Vernon County all the way to what is now the southern border of Bayfield County, excluding Pierce County and counties touching the Minnesota border north of Pierce.
