火地亚属（Hoodia），又名丽杯角属，是萝藦科下的一属开花植物。它们是肉质植物，有着像仙人掌的形态。它们可以生长达1米高，花朵很大，一般呈黄褐色及有强烈的气味。

大部份火地亚属物种都是受保护植物，分布在由纳米比亚中部至安哥拉南部的纳米比沙漠，尤其生长在平原及岩石区。

火地亚属有几个物种已被种植在花园内，而其中一种蝴蝶亚仙人掌更被研究用作抑制食欲。过往几年间，它们被大量采集作为减肥药。

于2008年，世界植物园保育协会（Botanic Gardens Conservation International）将400种草药列作有灭绝的风险，当中就包括了火地亚属。火地亚属正受到《濒危野生动植物种国际贸易公约》附录二的保护。

Hoodia /ˈhʊdiːə/ is a genus of flowering plants in the family Apocynaceae, under the subfamily Asclepiadoideae, native to Southern Africa. They are stem succulents, described as "cactiform" because of their remarkable similarity to the unrelated cactus family. They can reach up to 1 m high and have large flowers, often with a tan colour and strong smell. The group was first described as a genus in 1844. The genus became internationally known and threatened by collectors, after a marketing campaign falsely claiming that it was an appetite suppressant for weight loss.
