利吉丹岛（马来语：Pulau Ligitan）位于东马来西亚沙巴州东南西里伯斯海中，距仙本那 Tutop 角约12海里，卡帕莱岛以东12海里，西巴丹岛以东15海里。利吉丹岛属于利吉丹环礁中最大的一部分，位于环礁的最东端。整个环礁南北长约20公里，东西宽约15公里。岛南端建有一座灯塔。

该岛与西巴丹岛的主权曾在马来西亚和印度尼西亚两国之间存在争议。2002年国际法院裁决利吉丹岛和西巴丹岛的主权属于马来西亚。国际法院在裁决中指出，对于像利吉丹岛和西巴丹岛这样的无人居住或无人永久居住、且经济价值不大的争议地区，创建完善的行政机构进行有效控制通常很少见，因此，马来西亚在这些岛屿上所进行的控制和管理收集龟蛋、保护鸟类的、修建和维护灯塔和航行辅助物等措施，就足以构成实际控制。

Ligitan is a small island in Tawau, Sabah, located east of the island of Borneo, in the Celebes Sea. In the past, the island was at the centre of a territorial dispute between Malaysia and Indonesia. The matter was brought for adjudication before the International Court of Justice and, at the end of 2002, the Court awarded the island along with the island of Sipadan to Malaysia, on the basis of the "effective occupation" displayed by the latter's predecessor (Malaysia's former colonial power, Great Britain) and the absence of any other superior title. The Philippines had applied to intervene in the proceedings on the basis of its claim to Northern Borneo, but its request was turned down by the Court early in 2001.
