Heimdal Upper Secondary School (Norwegian: Heimdal videregående skole) is one of the largest upper secondary schools in the county of Trøndelag, Norway.

It is located about 10 km (6 mi) south of the city centre of Trondheim.

The school has approximately 700 students, 140 employees and the current headmaster is Ivar M. Husby.

During the 1970s the city of Trondheim was growing, and since Heimdal was growing relatively fast, it became natural to place an Upper Secondary School there.

In the middle of the 80s there was a total of around 900 students on the school (year 1985/86).
