The 2008 Delaware lieutenant gubernatorial election was held on November 4, 2008, coinciding with the Delaware gubernatorial election. Democratic nominee and Delaware State Insurance Commissioner Matthew Denn was elected lieutenant governor over Republican nominee and former State Senator Charlie Copeland in a landslide, succeeding incumbent John Carney, also a Democrat, who instead opted to run for governor.
Cullen withdrew from the race on September 29, but still appeared on the ballot.
