This is a partial list of secondary state highways in the U.S. state of Virginia. The numbers begin with 600 and can go into five digits in populous counties such as Fairfax County. The same number can be, and often is, assigned to secondary roads in more than one county. Because of the sheer number of secondary routes, this list is not intended to be a complete list.

For information about the creation and history of Virginia's Secondary Roads System, see article Byrd Road Act.

State Route 600 is a secondary state highway in the Eastern Shore of the U.S. state of Virginia. It runs 42.6 miles (68.6 km) north–south along Seaside Road, lying between U.S. Route 13 and the Atlantic Ocean, from a dead end at Kiptopeke north to State Route 605 near Locustville. SR 605 continues north on Seaside Road to Accomac, where US 13 leaves its alignment next to the Bay Coast Railroad to run closer to the ocean.

Most of SR 600 has never been a primary state highway, but the section from Kiptopeke north to SR 683 at Capeville was part of State Route 186 until 1951, when U.S. Route 13 was rerouted from Cape Charles to Kiptopeke.

SR 600 was numbered by 1934, and initially ran from SR 186 at Capeville to U.S. Route 13 in Accomac, using part of current State Route 605 to Accomac. It was extended south to Kiptopeke in 1951, replacing part of SR 186.
