John Handley High School (usually referred to as JHHS) is an endowed public high school located in the city of Winchester, Virginia. It is a part of Winchester Public Schools.

It was founded by a grant from Judge John Handley, hence the school mascot, the Judges. Construction on John Handley High School started in 1922, and continues to the present day. Recently, the school completed the final phase of its multimillion-dollar renovation with the addition of an 8-lane track and a turf football field. The school is planning renovations to its tennis courts in the upcoming years, due in part to the girls' three-peat state champions. In 1998, Handley was placed on the list of the National Register of Historic Places "for its local historic significance as well as its prominence as an architectural landmark."
