Virginia Senate, District 31

District 31 of the Virginia Senate is a senatorial district that encompasses portions of Arlington County, Fairfax County and Loudoun County in the U.S. state of Virginia. The current Senator from District 31 is Barbara Favola.

From 1940 to 1956, Senate District 31 comprised the counties of Caroline, Essex, Goochland, Hanover, King and Queen, King William and Middlesex.

Between 1956 - 1962, the district included the eastern end of the Virginia Peninsula comprising the counties of Mathews, Gloucester, Warwick, York, James City, New Kent, and the Independent City of Williamsburg.

From 1962 - 1964, the district included all of York County and the City of Hampton. From 1964 - 1968, the district included the City of Hampton and a portion of the City of Newport News. As a result of the United States Supreme Court's ruling in the case of Davis v. Mann regarding the principle of One person, one vote, the Virginia General Assembly was redistricted mid-decade and only 30 Senate districts were created, some of which were multi-member. Accordingly, there was no 31st District from 1968 - 1972.
