Rongerik Atoll or Rongdrik Atoll is an unpopulated coral atoll of 17 islands in the Pacific Ocean, and is located in the Ralik Chain of the Marshall Islands, approximately 200 kilometers east of Bikini Atoll. Its total land area is only 1.68 square kilometers, but it encloses a lagoon of 144 square kilometers.
In 1946, Rongerik was briefly inhabited by Bikini Islanders who, working with United States Navy moved here temporarily, when Bikini was used for conducting nuclear tests. However, the islanders could not get enough food to support the population, so after two years they had to relocate again, choosing Kili Island.
