Lake Huangqi, also known by its Chinese name as the Huangqi Hai, is a lake in Chahar Right Front Banner, Ulanqab Prefecture, Inner Mongolia, China. The lake has shrunk dramatically from its original size. Every year the lake looses more water to evaporation than is replenished by the now smaller rivers which feed it.
The present name dates to the Qing, when it was named after one of the Eight Banners.
