Virginia's 4th Senate district is one of 40 districts in the Senate of Virginia. It has been represented by Republican Ryan McDougle since his victory in a 2006 special election.
District 4 stretches from just outside Fredericksburg to the Chesapeake Bay, including all of the Northern Neck and parts of the Middle Peninsula. It covers all of Caroline, Essex, Middlesex, Lancaster, Northumberland, and Richmond Counties, as well as parts of Hanover, King George, Spotsylvania, and Westmoreland Counties.
The district overlaps with Virginia's 1st and 7th congressional districts, and with the 54th, 55th, 97th, 98th, and 99th districts of the Virginia House of Delegates.
All election results below took place prior to 2011 redistricting, and thus were under different district lines.
