The 1990 Illinois gubernatorial election occurred on November 6, 1990 to elect the governor and lieutenant governor of Illinois. Republican Jim Edgar, the Illinois Secretary of State, narrowly defeated Democrat Neil Hartigan, the Illinois Attorney General, by about 80,000 votes out of the over 3.2 million cast.
The incumbent Republican governor, Jim Thompson, chose not to seek a fifth term, making this the first open-seat gubernatorial election in Illinois since 1952. As of 2024, this is the second-closest Illinois gubernatorial election in the last 40 years, with only the 2010 race having a narrower margin.
