Little America was a series of Antarctic exploration bases from 1929 to 1958, located on the Ross Ice Shelf, south of the Bay of Whales.

The coordinates are approximate.

Location	Near Bay of Whales
Established	January 1929 (1929-01)
Abandoned	1930 (1930)

The first base in the series was established in January 1929 by Richard Byrd, and was abandoned in 1930. This was where the film With Byrd at the South Pole (1930), about Byrd's trip to the South Pole, was filmed.

Location	Near Bay of Whales
Established	1934 (1934)
Closed	1935 (1935)

Little America II was established in 1934, some thirty feet (ten meters) above the site of the original base, with some of the original base accessed via tunnel. This base was briefly set adrift in 1934, but the iceberg fused to the main glacier.

During the 1934–1935 expedition, many souvenir letters were sent from Little America, using a commemorative postage stamp issued by the U.S. government. The souvenir cancellation operations were conducted under extremely difficult conditions.

Little America established the first successful radio broadcasting from Antarctica, making regular broadcasts that could be picked up by household radio sets in the United States, more than 11,000 miles (18,000 kilometers) away around the Earth's curvature.

In a later expedition to Antarctica, Byrd's expedition spotted Little America's towers still standing, including the Jacobs Wind plant installed in 1933.

Little America III
Coordinates: 78°35′00″S 163°52′00″W / 78.5833°S 163.8667°W / -78.5833; -163.8667 (Little America III)
Location	Near Bay of Whales
Established	1940 (1940)
Abandoned	1940 (1940)

Little America III was established for the 1940–1941 season, some six miles (ten kilometers) to the north.

In 1940 a huge exploration vehicle, the Antarctic Snow Cruiser, was brought to Little America III. Unfortunately, the vehicle was found to have a number of design and technical weaknesses and was little used. Abandoned, it became buried in the snow. It was last rediscovered in 1958, but has subsequently been lost once again, either under the snow, or under the waters of the Southern Ocean.

The site of Little America III was carried to sea in 1963.

Little America IV
The camp established as US Navy's Operation Highjump, 1946–1947
Coordinates: 78°33′00″S 163°56′00″W / 78.5500°S 163.9333°W / -78.5500; -163.9333 (Little America IV)
Location	Near Bay of Whales
Established	December 1946 (1946-12)
Closed	1947 (1947)

Little America IV was established in 1946–1947 as the primary camp for Operation Highjump. On 2 and 5 December 1946, 166 Seabees sailed from Port Hueneme on the USS Yancey and USS Merrick assigned to Operation Highjump.

Little America V
Coordinates: 78°19′00″S 162°22′00″W / 78.3167°S 162.3667°W / -78.3167; -162.3667 (Little America V)
Location	Near Kainan Bay
Established	3 January 1956 (1956-01-03)
Closed	31 December 1958 (1958-12-31)

Little America V was established on January 3, 1956, at Kainan Bay, some 30 miles (50 kilometers) east of Little America IV, as part of Operation Deep Freeze. Little America V served as the American base in the South Polar program in the International Geophysical Year, from July 1, 1957, to December 31, 1958. Little America V was constructed by United States Navy Seabees in the three-month window before the Antarctic winter makes construction nearly impossible. All of Little America V was constructed below the snow line in the ice, with individual living quarters, generator room, cafeteria, and with ramps leading out at one end for tracked vehicles. This type of construction meant that none of those staying in Little America V had to go outdoors in the harsh winter when going from one section to another of the Antarctic town.

The site of Little America V went to sea on Iceberg B-9 in 1987.

Little America V was one of seven bases that the United States built for the IGY, which also included McMurdo, Hallett, Wilkes, Admundsen-Scott (South Pole Station), Ellsworth, and Byrd.
