垒固（缅甸语：လွိုင်ကော်မြို့，Loi-kaw或Loikaw）是缅甸克耶邦的首府，人口约一万一千人。垒固位于克耶邦的北端，高度约1200公尺。垒固的居民大部分是克耶族（或称克伦尼族）。缅甸最大的水力发电站——洛皮塔（Lawpita）水力发电站就位于距离垒固东方二十公里的洛皮塔瀑布（Lawpita Falls）处。该发电站是由日本人所建以做为战争赔偿。垒固有一条新建的铁路。

Loikaw (Burmese: လွိုင်ကော်မြို့; MLCTS: lwing kaw mrui., pronounced: [lwàikɔ̀ mjo̰]) is the capital of Kayah State in Myanmar. It is located in the Karen Hills area, near the State's northern tip, just above an embayment on the Pilu River. The inhabitants are mostly Kayah (Karenni). Myanmar's largest hydropower plant built (by the Japanese as war reparation) is located about 20 km east of Loikaw at Lawpita Falls.
