The Tarnovo Literary School (Bulgarian: Търновска книжовна школа) of the late 14th and 15th century was a major medieval Bulgarian cultural academy with important contribution to the Medieval Bulgarian literature established in the capital of Bulgaria Tarnovo. It was part of the Tarnovo School of Art which was characteristic for the culture of the Second Bulgarian Empire.
With the orthographic reform of Saint Evtimiy of Tarnovo and prominent representatives such as Gregory Tsamblak or Constantine of Kostenets the school influenced Russian, Serbian, Wallachian and Moldavian medieval culture. It is well known in Russia as the second South Slavic influence.
