Owyhee is a census-designated place (CDP) in Elko County, Nevada, United States. The population was 1,017 at the 2000 census. It is part of the Elko Micropolitan Statistical Area.
Owyhee is within the Duck Valley Indian Reservation, and since about half the reservation is also located in southwestern Idaho, the Nevada portion of the reservation observes Mountain Time. Owyhee and nearby Mountain City (located 12 miles southeast of Owyhee and 2 miles southeast of the reservation boundary) are not exempt from state legislation which places them officially in the Pacific Time Zone. However, the residents of Owyhee observe Mountain Time regardless.
Owyhee is located at 41°56′53″N 116°8′7″W / 41.94806°N 116.13528°W / 41.94806; -116.13528 (41.947928, -116.135181).
