Nikudin Rock (Bulgarian: скала Никудин, ‘Skala Nikudin’ \ska-'la ni-ku-'din\) is the high, round rock of diameter 180 m and split in northeast-southwest direction, lying off the north coast of Greenwich Island in the South Shetland Islands. The area was visited by early 19th century sealers.
The rock is named after the settlement of Nikudin in Southwestern Bulgaria.
