Istanbul Şehir University (Turkish: İstanbul Şehir Üniversitesi, literally City University of Istanbul) was a private, non-profit university located in Istanbul, Turkey. It was established in 2008 by the Bilim ve Sanat Vakfı (BiSaV or BSV, English: Foundation for Science and Arts). The university started its education in the academic year of 2010–11 at its campus in Altunizade, Üsküdar, following a ceremony held on October 5, 2010 that was attended by then State President Abdullah Gül, Prime Minister Recep Tayyip Erdoğan and Minister of Foreign Affairs Ahmet Davutoğlu. The university was closed down on June 30, 2020, after it faced financial difficulties stemming from a legal land dispute, which in turn was fueled by a bitter political feud.
