Yunak Stadium (Bulgarian: Стадион Юнак, Stadion Yunak), was a multi-use stadium in central Sofia, Bulgaria. It was located at the north-western corner of Knyaz Boris's Garden, on the southern bank of the Perlovska river. It was the largest stadium in Bulgaria until the middle of the 20th century, with a capacity of 35,000 spectators, and was initially used as the main stadium for Bulgaria national football team matches. The pitch was almost exactly square-shaped, with four straight rows of stands on all sides.
