Kadıköy Anatolian High School (Turkish: Kadıköy Anadolu Lisesi), also commonly known as Kadıköy Maarif College, abbreviated Kadıköy Maarif or KAL, is one of the oldest, most prestigious Anatolian High Schools and internationally renowned high schools of Turkey; located in Moda, Istanbul. The education languages are Turkish and English. Secondary foreign language offered is German.

The original building, which unfortunately exists no more, dates back to before World War I and was built by the Franciscan Capuchin Order. The building was inhabited by the followers of this sect for many years. After the National Ministry of Education decided to open a high school in Kadikoy district, negotiations that lasted many years took place between the ministry and the Capuchins. In 1955 the school opened as Kadıköy Maarif. In 1968 a second building was added to the school which served as a dormitory. In 1976 and 1977 two more buildings were added. For many years it was ranked as the biggest highschool in the Balkans.

After a new education structure was established by the Ministry of Education, the School's name changed from Kadıköy Maarif Koleji to its present name, Kadıköy Anadolu Lisesi (KAL). Like Galatasaray High School and Istanbul High School, it used to have a 2-year English preparation period with a following independent curriculum, but in 2006 KAL adopted the regular 4-year lycee education following a 1-year prep period. With over 1500 students, and a 94.1% university entrance ratio, it is, and always has been one of the most important high schools in Turkey.
