Arno Atoll (Marshallese: Arņo, [ɑnnˠɔ][1]) is a coral atoll of 133 islands in the Pacific Ocean, and forms a legislative district of the Ratak Chain of the Marshall Islands. Its total land area is only 5 square miles (13 km2). Unlike most other atolls, Arno encloses three different lagoons, a large central one, and two smaller ones in the north and east. Its main lagoon encloses an area of 130.77 square miles (338.7 km2). At a distance of only 20 kilometers (12 mi), it is the closest atoll to the Marshall Islands capital, Majuro Atoll, and can be seen looking east from Majuro on a clear day at low tide. The population of Arno Atoll was 1,794 at the 2011 census. The most populous islets are Ajeltokrok, Kobjeltak, Rearlaplap, Langor and Tutu. The largest village is Ine, Arno.

People of Arno are well known for their productivity in making copra (the dried out meat of coconuts, from which coconut oil is extracted). Arno women are renowned for their production of the Kili Bag, a popular handwoven handbag/purse, named after another island in the Marshall Islands (to which the people of Bikini were eventually relocated as a result of the US nuclear tests that were conducted on their home atoll). Arno supposedly had a traditional "love school".


Arno Atoll was claimed by the Empire of Germany along with the rest of the Marshall Islands in 1884. After World War I, the island came under the South Seas Mandate of the Empire of Japan. Following the end of World War II, Arno Atoll came under the control of the United States as part of the Trust Territory of the Pacific Islands. The island has been part of the independent Republic of the Marshall Islands since 1986.
