United World College of the Adriatic (UWC Adriatic or UWCAd ) is a part of the United World Colleges, a global educational movement that brings together students from all over the world with the aim to foster peace and international understanding. The school is attended by around 200 mixed-gender students aged between 16 and 19, mostly on full scholarship, from around 90 countries of the world, who study the International Baccalaureate Diploma Programme, a two-year internationally recognized pre-university program.

The school is hosted in the village of Duino, between Trieste and Monfalcone, in north-eastern Italy in the region of Friuli Venezia Giulia, less than 5 km from the Slovenian border. It was founded in 1982, by the region of Friuli Venezia Giulia, with the support of the Italian government (Ministry of Foreign Affairs), who are still the major financial supporters of the college. The founding headmaster of the college was David B. Sutcliffe, an influential part of the United World Colleges's movement and follower of the Kurt Hahn educational philosophy.
