The Tundzha (Bulgarian: Тунджа [ˈtund͡ʒɐ]; Turkish: Tunca [tund͡ʒa]; Tonsus in antiquity) is a river in southeastern Bulgaria and northwesternmost Turkey, a left tributary of the Maritsa. With a length of 390 km, of which 350 km are in Bulgaria, it is Maritsa's longest tributary, though in terms of discharge it is second after the Arda. Tundzha Glacier on Livingston Island in the South Shetland Islands, Antarctica is named after Tundzha River.
