北赛普勒斯（土耳其语：Kuzey Kıbrıs），全称北赛普勒斯土耳其共和国（Kuzey Kıbrıs Türk Cumhuriyeti，缩写为KKTC，英文全称为Turkish Republic of Northern Cyprus，英文缩写为TRNC）是一个位于赛普勒斯岛北部，尚未受到国际承认的政治实体。北赛普勒斯是在1974年由赛普勒斯岛上的土耳其人后裔宣布独立建国，政权控制了岛上北边约1/3面积的领土，但目前全世界只有土耳其承认北赛普勒斯的政权。北赛普勒斯与岛南的希腊裔政权皆占有首都尼古西亚（土耳其语：Lefkoşa，希腊语：Λευκωσία）部份范围，因此双方皆以该城作为首都，其中北塞浦路斯占有的部分被称为北尼科西亚。

Northern Cyprus (Turkish:Kuzey Kıbrıs), officially the Turkish Republic of Northern Cyprus (TRNC; Turkish:Kuzey Kıbrıs Türk Cumhuriyeti), is a self-declared state that comprises the northeastern portion of the island of Cyprus. Recognised only by Turkey, Northern Cyprus is considered by the international community to be part of the Republic of Cyprus.
