The 2006 United States Senate election in Virginia was held November 7, 2006. Incumbent Republican Senator George Allen ran for reelection to a second term but was narrowly defeated by former Secretary of the Navy Jim Webb, who earned 49.6% of the vote to Allen's 49.2%. With a margin of just 0.4%, this election was the closest race of the 2006 Senate election cycle. This was the second consecutive election for this seat where the incumbent lost re-election. Webb did not seek reelection in 2012, and was succeeded by fellow Democrat Tim Kaine, who defeated Allen by 5.9 percentage points to win the open seat.
