Virginia's 11th congressional district

Virginia's 11th congressional district is a U.S. congressional district in the Commonwealth of Virginia. Situated in the Northern Virginia suburbs, the district comprises most of Fairfax County and the entirety of Fairfax City. The district is currently vacant, and was most recently represented by Democrat Gerry Connolly, who died in office on May 21, 2025.

The Hill newspaper quotes census data to conclude that Virginia's 11th district was the wealthiest congressional district in the nation from 2003 to 2013. The article attributed the wealth to "the presence of high-level federal workers and two-income families" and because "lobbyists and other corporate types flock to the D.C. area."

The district last existed in what is now West Virginia's 1st district and was held by Jacob B. Blair before the events of the U.S. Civil War. Virginia did not have an 11th district until it was re-created after the 1990 United States census from portions of the old 8th and 10th districts because of explosive growth in Northern Virginia. It was intended to be a "fair fight" district; indeed, it encompassed most of the more Democratic portions of the old 10th district and the more Republican portions of the old 8th district.

George W. Bush only narrowly defeated John Kerry here in 2004, while Democratic Governor Tim Kaine and Democratic Senator Jim Webb both carried this district, in 2005 and 2006 respectively. In 2008, Barack Obama won this district over Republican Senator John McCain. As of 2025, the last time Republicans won this district was in the 2009 Virginia gubernatorial election, when Republican Bob McDonnell carried it, along with incumbent Lieutenant Governor Bill Bolling in the lieutenant gubernatorial race. Democrat Leslie Byrne briefly held the seat for the first election cycle of the new district, but was quickly defeated in 1994 by Republican Tom Davis. Davis established a secure hold on the district during his tenure (1995–2008), but Democrat Gerry Connolly won it when Davis announced retirement and later resigned before his term ended.

Both Davis and Connolly may have been aided by their previous service on the Board of Supervisors of Fairfax County, where most of the 11th district's population is concentrated. 96.7% of 11th congressional district residents live in Fairfax County, with the remaining 3.3% living in Fairfax City.
