Ninian Edwards (March 17, 1775July 20, 1833) was a founding political figure of the State of Illinois. He served as the first and only governor of the Illinois Territory from 1809 to until the territory was dissolved in 1818. He was then one of the first two United States Senators from the State of Illinois from 1818 to 1824, and the third Governor of Illinois from 1826 to 1830. In a time and place where personal coalitions were more influential than parties, Edwards led one of the two main factions in frontier Illinois politics.
