Bikini Atoll (pronounced /ˈbɪk.ɨˌniː/ or /bɨˈkiː.ni/; Marshallese: Pikinni, [pʲi͡ɯɡɯ͡inʲːii̯], meaning coconut place) is an atoll in the Marshall Islands. The atoll consists of 23 islands totaling 3.4 square miles (8.8 km²) surrounding a deep 229.4-square-mile (594.1 km²) central lagoon at the northern end of the Ralik Chain (approximately 87 kilometres (54 mi) northwest of Ailinginae Atoll and 850 kilometres (530 mi) northwest of Majuro). Within Bikini Atoll, Bikini, Eneu, Nam and Enidrik islands comprise just over 70% of the land area. Bikini and Eneu are the only islands of the atoll that hosted a permanent population. Bikini Island is the northeastern most and largest islet.
