Jonstrup is a suburban neighbourhood situated in Furesø Municipality on the west side of Hareskoven forest in the northwestern outskirts of Copenhagen, Denmark.
The neighbourhood is separated from Måløv by Mølledalen, Møllemosen, and Værebro Å.
In 1809, it was converted into a teachers' academy, Jonstrup Seminarium, which moved to new premises in Kongens Lyngby in 1955.
Conveniently located close to the Værløse Air Base, the buildings in Jonstrup were then acquired by the Danish military and converted into the new Royal Danish Air Force Officers School.
In 1998, Værløse Municipality acquired the building and converted it into a primary school.
