Prudhoe Bay is a census-designated place (CDP) located in North Slope Borough in the U.S. state of Alaska. As of the 2000 census, the population of the CDP was 5. According to the United States Census Bureau, it is one of only eight places in the United States with a population of five people. The others are Storrie, California; Bear Head Lake, Minnesota; Baker, Missouri; Gross, Nebraska; Odell, New Hampshire; Maza, North Dakota; and Somerset, Vermont.
Despite the low census, Prudhoe Bay is a busy place. Several thousand temporary workers support the Prudhoe Bay oil field. The airport, lodging, and general store are located at Deadhorse; the rigs and processing facilities are located on scattered gravel pads laid atop the tundra. Only during winter is the surface hard enough to support heavy equipment; new construction happens then.
A few tourists, arriving by bus after a two-day ride up the Dalton Highway from Fairbanks, come to see the tundra, the Arctic Ocean, and the midnight sun, staying in lodgings assembled from modular buildings.
Prudhoe Bay was named in 1826 by British explorer Sir John Franklin after his classmate Captain Algernon Percy, Baron Prudhoe.
Prudhoe Bay is located at (70.325490, -148.711387).
According to the United States Census Bureau, the CDP has a total area of 558.0 square miles (1,445.3 km²), of which, 416.3 square miles (1,078.1 km²) of it is land and 141.8 square miles (367.2 km²) of it is water. The total area is 25.40% water.
