Kantonsschule Stadelhofen (KST) in Zürich-Stadelhofen is an upper secondary school in the Canton of Zürich in Switzerland.

KST is organized as a public high school that is teaching on the level of the maturity profiles altsprachlich (classical languages), neusprachlich (modern languages), musisch (fine arts), and mathematisch-naturwissenschaftlich (mathematical and natural sciences).

The school in its present form was established in 1975, but its predecessing institution dates back to the former Töchterschule der Stadt Zürich which was established in 1874.

As Bluntschli served also as the architect for the construction of the Enge Church on the opposite Zürichsee lake shore, there ary many similarities in the construction.

Surrounded by a beautiful park, the building now houses premises of the adjacent Stadelhofen college.
