2010 Connecticut Attorney General election

The 2010 Connecticut attorney general election was held on Tuesday, November 2, 2010, to elect the 24th attorney general of the state of Connecticut. Five-term incumbent attorney general Richard Blumenthal declined to seek re-election in 2010, instead opting to run for Connecticut's open U.S. Senate seat held by the retiring Christopher Dodd. Blumenthal's decision not to seek a sixth term set-up the first open race for attorney general in the state since Blumenthal's election in 1990.

At their May 2010 state convention, Democratic candidate George Jepsen won the endorsement of his party outright and did not face a primary challenger. The Republican candidate, Martha Dean, secured her party's nomination via a primary election defeat of Ross Garber on August 10.
