James Ross Island (64°10′S 57°45′W) is a large island off the southeast side and near the northeastern extremity of Antarctic Peninsula, from which it is separated by Prince Gustav Channel. Rising to 1,630 m, it is irregularly shaped and extends 40 miles in a north-south direction. It was charted in October 1903 by the Swedish Antarctic Expedition under Otto Nordenskiöld. He named it for Sir James Clark Ross, leader of a British expedition to this area in 1842, who discovered and roughly charted a number of points along the eastern side of the island. The form James Ross Island is used to avoid confusion with the more widely known Ross Island in McMurdo Sound.

The first Czech Antarctic Base is located on the island.
