1798 Connecticut lieutenant gubernatorial election

The 1798 Connecticut lieutenant gubernatorial election was held on April 9, 1798, in order to elect the lieutenant governor of Connecticut. Federalist candidate John Treadwell won a plurality of the vote against candidate and former member of the U.S. House of Representatives from Connecticut's at-large district Jonathan Sturges, fellow Federalist candidate and incumbent United States Senator from Connecticut James Hillhouse and other candidates. However, as no candidate received a majority of the total votes cast as was required by Connecticut law, the election was forwarded to the Connecticut legislature, who chose Treadwell as lieutenant governor.
