Arno Atoll, one of the main atolls of the Marshall Islands, is located in the southern regions of the groups Ratak Chain some 15 km east of Majuro. The atoll has an irregular shape consisting of a narrow reef rim that encloses a large and deep lagoon of 339 km².
With a land area of nearly 13 km², Arno Atoll has a large number of islets (133), with much of the southern side of the atoll consisting of a single, twisting ribbon of continuous land that forms the island of Ajeltokrok. The atoll exhibits an unusual feature of having two "pinched-lagoons" — one each in the northeast and northwest — in effect creating three separate lagoons.
The most populous of Arno's islets are Ajeltokrok, Kobjeltak, Rearlaplap, Langor and Tutu.
