The AAA Western Valley District was a high school conference in the state of Virginia that included the small number of schools in Central and Southwest Virginia which competed in Group AAA, is largest enrollment class of the Virginia High School League.
The Western Valley District schools competed in the AAA Northwest Region with the schools from the AAA Cardinal District, the AAA Cedar Run District, and the AAA Commonwealth District.
In the 2013-2014 school year, the schools of the Western Valley District were assigned to the previously Group AA based AA River Ridge District, AA Blue Ridge District, and AA Piedmont District. In the post-season, each school will compete against members of the same group classification only.
The Western Valley District was established in 2001 to consolidate the now defunct AAA Roanoke Valley District and the AAA Western District. The two districts' memberships had dwindled to five and four members respectively. Many schools in these districts had either lost student population or had experienced slow growth compared to the rest of Virginia, which made them eligible to drop to Group AA. In 2001, two of the five members of the Roanoke Valley district dropped to the AA Blue Ridge District, prompting the consolidation with the Western district. Below is a list of the Roanoke Valley and Western Districts in the 2000-2001 school year, and their districts for the 2001-2002 school year:

Cave Spring's student body was split to form Hidden Valley High School (Roanoke, Virginia) in 2002. Both schools joined AA for the 2003-2004 school year, which reduced the district to five members. In 2007, William Fleming of Roanoke returned to the district because of increased enrollment, reuniting it with cross-town rival Patrick Henry.
