Jemo Island Atoll (Marshallese: Jemo̧ or Jāmo̧, [tʲææ̯mʲæ͡ɒɒ̯]) is an uninhabited coral island in the Pacific Ocean, in the Ratak Chain of the Marshall Islands north-east of Likiep Atoll. The island is oval-shaped, and occupies the southwestern end of a narrow submarine ridge that extends to the northeast for several kilometers. Its total land area is only 0.16 square kilometres (0.062 sq mi). The island is traditionally held as a food reserve for the family of Joachim and Lijoan deBrum, passed down from Iroijlaplap Jortoka Lobareo and is owned by the current Likiep land-owning families of Joachim debrum.
First recorded sighting of Jemo Island by Europeans was by the Spanish expedition of Miguel López de Legazpi on 10 January 1565. It was charted as Los Pajaros (The Birds in Spanish).
