The Phrontisterion of Trapezous (Greek: Φροντιστήριο Τραπεζούντος, "Trapezous College") was a Greek educational institution that operated from 1682/3 to 1921 in Trabzon (Gr. Τραπεζούς, Trapezous), in the Ottoman Empire, now Turkey. It provided a major impetus for the rapid expansion of Greek education throughout the Pontus region, on the south coast of the Black Sea. The building still retains its function as a prestigious highschool, and it has been considered as the most impressive Pontic Greek monument in Trabzon.
