Fruzhin (Bulgarian: Фружин; also transliterated Fružin or Frujin; died c. 1460) was a 15th-century Bulgarian noble who fought actively against the Ottoman conquest of the Second Bulgarian Empire. A son of one of the last Bulgarian tsars, Ivan Shishman of the Tarnovo Tsardom, Fruzhin co-organized the so-called Uprising of Konstantin and Fruzhin along with Constantine II of Vidin, the last medieval Bulgarian monarch. Fruzhin was mainly based in the Kingdom of Hungary, where he was the ruler of Temes County.
