Jon P. Wilcox (born September 5, 1936)[1] is an American lawyer and retired judge. He was a justice of the Wisconsin Supreme Court for 15 years, appointed by Governor Tommy G. Thompson in 1992 and leaving office in 2007. Prior to his time on the Supreme Court, he served for 13 years as a Wisconsin Circuit Court Judge, including seven years as Chief Judge of the 6th Judicial Administrative District of Wisconsin Circuit Courts. Earlier, he represented Green Lake and Waushara counties in the Wisconsin State Assembly as a Republican.

In the Fall of 2023, Wilcox was one of three former Wisconsin Supreme Court justices who advised Assembly speaker Robin Vos on the question of whether to impeach new justice Janet Protasiewicz. Wilcox released his opinion to the press on October 11, 2023, saying that he "did not see that there were any impeachable offenses."[2]
