Sun Valley High School (SVHS) is a public high school in Union County, North Carolina. Sun Valley is part of Union County Public Schools. It is located between Monroe and Indian Trail.
Sun Valley was founded in 1961. For decades, it was the only high school in western Union County. Three new high schools have been built in the area since the 2000s, partially relieving the crowded conditions that persisted at the school for many years.
The school presently serves all of Wesley Chapel, eastern Indian Trail, eastern Weddington and part of western Monroe. This was a result of redistricting on behalf of the Union County Public School board.
