The Illinois gubernatorial election of 1842 was the eighth quadrennial election for this office. DemocratAugustus C. French defeated Whig nominee Thomas M. Kilpatrick,for the office. Richard Eels of the Liberty Party came in a distant third. The term was cut short, and lasted only half the normal length. This synchronized the gubernatorial election with the election for President. This was the first time in the history of the state that a governor was re-elected, though governor Joseph Duncanattempted this and failed.
