Kianida Reef (Bulgarian: риф Кианида, romanized: rif Kianida, IPA: [ˈrif kiɐˈnidɐ]) is the 350 m long in east-west direction and 140 m wide, narrowing to the east rocky reef lying in Osogovo Bay, off the southeast extremity of Rugged Island in the South Shetland Islands. Its surface area is 4 ha. The area was visited by early 19th century sealers.
The feature is named after the phantom island of Kianida or Cianeis off the Black Sea coast of Thrace, featured on a 1467 map by Nicolaus Germanus based on Claudius Ptolemy's Geography.
