St. Ivan Island (Bulgarian: остров св. Иван, ostrov sv. Ivan) is the largest Bulgarian island in the Black Sea, with an area of 0.66 square kilometres (0.25 sq mi). It lies off the Bulgarian Black Sea Coast near Sozopol, a town with rich history and a popular tourist place, and is separated by a strait several hundred metres long from the small neighbouring St. Peter Island. Standing at 33 metres (108 ft) above sea level, it is also the highest of the Bulgarian sea islands.
