菲尼克斯群岛（Phoenix Islands），是基里巴斯三大主要岛群之一，位于吉尔伯特群岛以东、莱恩群岛以西。

1930年代时英国一度计划开发此群岛，但未付诸实施。后美国也曾对此岛提出过领土要求，但在基里巴斯独立后即放弃。

菲尼克斯群岛几乎完全无人居住，2005年人口统计发现全群岛的人口仅41人。

The Phoenix Islands are a group of eight atolls and two submerged coral reefs, lying in the central Pacific Ocean east of the Gilbert Islands and west of the Line Islands. They are a part of the Republic of Kiribati. During the late 1930s they became the site of the last attempted colonial expansion of the British Empire through the Phoenix Islands Settlement Scheme. The Phoenix Islands Protected Area, established in 2008, is one of the world's largest protected areas, and home to some 120 species of coral and more than 500 species of fish.
