The Connecticut gubernatorial election of 2006 occurred on November 7, 2006. Incumbent Republican Jodi Rell became governor when John G. Rowland resigned on corruption charges in 2004. Rell was very popular, with an approval rating of 70% as of October 19, 2006.  Polls showed her leading the Democratic nominee, New Haven mayor John DeStefano by a near 30-point margin. As expected, she won election to a full term in a landslide.
DeStefano defeated Stamford Mayor Dan Malloy in the Connecticut Democratic gubernatorial primary on August 8. As of 2019, this is the most recent time a Republican was elected Governor of Connecticut.
