The Jaume I University (Spanish: Universidad Jaume I, Valencian: Universitat Jaume I, UJI; IPA: [univeɾsiˈtad ˈdʒawme priˈmeɾ]) is a university in the city of Castellón de la Plana, Spain. It was founded in 1991, and in 2014 there were approximately 15,000 students enrolled. It is named after Jaume I, the king who founded the Kingdom of Valencia.
Universitat Jaume I is currently the leading higher education and research centre in the north of the Valencian Community and it is continually seeking to enhance the social, economic and cultural development of the society in which it is immersed through the creation and transmission of knowledge. In this sense UJI has always wanted to play an active role, as shown by initiatives such as the opening of new off-campus offices in the different areas throughout the province of Castelló, its extramural activities, or its collaboration with the UJI Alumni and Friends Society (SAUJI).
