Map - Ebon Atoll (Ebon Atoll)

Ebon Atoll (Marshallese: Epoon, ) is a coral atoll of 22 islands in the Pacific Ocean, forming a legislative district of the Ralik Chain of the Marshall Islands. Its land area is 5.75 km2, and it encloses a deep lagoon with an area of 104 km2. A winding passage, the Ebon Channel, leads to the lagoon from the southwest edge of the atoll. Ebon Atoll is approximately 155 km south of Jaluit, and it is the southernmost land mass of the Marshall Islands, on the southern extremity of the Ralik Chain. In documents and accounts from the 1800s, it was also known as Boston, Covell's Group, Fourteen Islands, and Linnez.

Ebon Atoll was visited by commercial whaling vessels in the 19th century. The first such vessel on record was the Newark in 1837. The last whaler known to have visited was the Andrew Hicks in 1905.

The schooner Glencoe was taken and its crew massacred by Marshallese at Ebon in 1851 – one of three vessels attacked in the Marshall Islands in 1851 and 1852. There were several motives, and by some accounts the ship's crew had been abducting island women for sale to plantation owners (slavery) at other destinations.

Missionaries sent by the American Board of Commissioners for Foreign Missions in Boston began missionary activities in the Marshall Islands in 1857, establishing a mission at Ebon.

Ebon was claimed by the Empire of Germany along with the rest of the Marshall Islands in 1884, and the Germans established a trading outpost. After World War I, the island came under the South Seas Mandate of the Empire of Japan, which had a garrison there late in World War II. The base became part of the vast US Naval Base Marshall Islands. At the end of WW II, Ebon Atoll became a part of the Trust Territory of the Pacific Islands under the control of the United States, until the independence of the Marshall Islands in 1986.

On January 30, 2014, castaway José Salvador Alvarenga, a Salvadorian national who had been working in Mexico as a fisherman, was found by locals from Ebon after he had pulled his boat ashore on Enienaitok Islet at the conclusion of a 14-month drifting voyage of 10,800 kilometers (6,700 miles) across the Pacific.
