Markgama, or Markham Island (Russian: Остров Маркгама, literally "Island of Markham") is a small, isolated island in the southern region of the Kara Sea off the Sorevnovaniya Bay. This island has only sparse tundra vegetation and it is covered with snow most of the year. The coast of the Taymyr Peninsula is located 15 km to the southeast.
The island's length is only 2 km and its maximum width 1.5 km. The sea surrounding it is covered with pack ice with some polynias in the long winter and there are many ice floes even in the summer.
Markgama belongs to the Krasnoyarsk Krai administrative division of the Russian Federation. It is also part of the Great Arctic State Nature Reserve – the largest nature reserve of Russia and one of the biggest in the world.
The area around Markgama was explored by Otto Sverdrup on ship Eklips in 1914 while he was searching for Brusilov and Rusanov. The island was named by Fridtjof Nansen after British Arctic explorer Clements Robert Markham in 1893.
