Kuleli Military High School was the oldest military high school in Turkey, located in Çengelköy, Istanbul, on the Asian shore of the Bosphorus strait. It was founded on 21 September 1845, by Ottoman Sultan Abdülmecid I.

After the 2016 Turkish coup d'état attempt Kuleli Military High School along with other Military High Schools was closed and turned into a museum. The building was later converted into a Language School where foreign languages were taught to military personnel.
