Jameson Land is a peninsula in eastern Greenland.
Jameson Land is bounded to the southwest by Scoresby Sound (the world's largest fjord), to the northwest by the Stauning Alps, to the north by Scoresby Land, to the northeast by the Fleming Fjord and the Nathorst Fjord of the Greenland Sea, and to the east by Carlsberg Fjord, the smaller Liverpool Land peninsula branching off, and Hurry Inlet. Its northeastern end is Cape Biot.
The Mestersvig military base is located in the northern part of the peninsula.
Jameson Land mainly consists of a tilted peneplain of jurassic sandstone, highest in the east. In the northern end there are also rocks of triassic origin. Two formations are predominant in Jameson Land: the Triassic Fleming Fjord Formation and the Jurassic Kap Stewart Formation. Jameson land triassic fossils of Flamming Fjord Formation include: dipnoi Ceratodus, prosauropod and theropod dinosaurs bones and tracks, sauropod tracks, phytosaurs, temnospondyls, and sharks.
