Virginia's 12th House of Delegates district

Virginia's 12th House of Delegates district elects one of the hundred Delegates of the Virginia House of Delegates, United States.

Under redistricting effective for the 2023 Virginia House of Delegates election, the 12th district number was reassigned to part of northern Virginia's Fairfax County, while the district number 42, previously used elsewhere in Fairfax, was applied to a new southwestern district including most of the old 12th.

The new District 12 in the Tysons and Vienna area, includes parts of the old districts 34, 35, 37, 39, 41 and 53.

The current Delegate is Democrat Holly Seibold

Before redistricting, the old 12th included the city of Radford, Giles County, and portions of Montgomery County and Pulaski County. After redistricting, most of the old 12th became part of the new 42nd district, formed from parts of the previous districts 12, 7 and 8, still including Radford City and all of Giles County, but incorporating different parts of Pulaski and Montgomery counties. Significantly, the new district no longer includes the Montgomery County town of Blacksburg, which had been home to previous Democrat delegates from the 12th, Joan Munford, Jim Shuler and Chris Hurst.
