Grennaskolan, (spelled Grännaskolan until 1995) is a boarding school in the Swedish town of Gränna which was formerly one of Sweden’s three national boarding schools. The main building, Borgmästargården, dating from 1797, is situated beside Gränna’s main square and surrounded by a large garden with a view of Grännaberget. Most of the school buildings and student dormitories are located on Bergsgatan. Grennaskolan was founded in 1963 by Stockholm University. Today Grenna International Campus AB is a wholly owned subsidiary of Rådhus AB, which is owned by Jönköping Municipality.
Approximately half the students at Grennaskolan are boarders and half are day students. The school has room for 145 boarders accommodated in six houses.
At upper secondary school level, Grennaskolan offers education within Swedish national upper secondary school programmes (Natural Sciences Programme and Social Sciences Programme with various orientations) and the IB Diploma Programme (International Baccalaureate). There is also an introductory course for students with Swedish parents living abroad. The school also offers education at junior high school level (years 7–9) with an international profile.
