Suemez Island is located in the Alexander Archipelago of southeastern Alaska, United States.
Suemez Island has a land area of 151.713 km2 (58.5768 sq mi) and was unpopulated at the 2000 census.
Dionisio Alcalá Galiano called it "Guemes" in his map published in 1802, which may be the proper spelling.
The name "Guemes" honors Juan Vicente de Güemes Padilla Horcasitas y Aguayo, Viceroy of New Spain from 1789 to 1794.
[2] It is the only place in the world where the Suemez Island ermine (Mustela haidarum seclusa) can be found.
