Jonathan Ingersoll (April 16, 1747 – January 12, 1823) was a Connecticut politician of the late eighteenth and early nineteenth centuries.
He was graduated from Yale College in 1766. He was elected as a member representing his state at-large in the United States House of Representatives, by a special election on September 16, 1793 (to replace Congressman-elect Benjamin Huntington who had become a Judge). However he declined this office before the 3rd Congress convened, so he was never sworn in. A replacement was elected at a special election on November 11, 1793. He served as Superior court judge in Connecticut, 1798–1801 and 1811–1816.
