蓝马羚（Hippotragus leucophaeus）是一种已灭绝的羚羊，且是非洲最早消失的大型哺乳动物。牠们与马羚及黑马羚是近亲，但略为细小。牠们生活在南非东南海岸的大草原，在冰河时期的分布更为广泛。牠们可能是择食性的，较为喜欢吃优质的草。

于17世纪，欧洲殖民大量杀死稀少的蓝马羚，目的是要将牠们的栖息地改变为农地。牠们约于1800年灭绝，现时只有四个博物馆存有牠们架起的标本，分别是在维也纳、斯德哥尔摩、巴黎及莱顿，并且在其他地方有一些牠们的骨头及角。所架起的标本并没有呈蓝色，估计牠们的蓝色是来自黑色及黄色毛皮的混合。

The bluebuck or blue antelope (Hippotragus leucophaeus), sometimes called blaubok, is an extinct species of antelope, the first large African mammal to disappear in historic times. It is related to the roan antelope and sable antelope, but slightly smaller than either. It lived in the southwestern coastal region of South Africa savannas, but was more widespread during the last glacial. It was probably a selective feeder, preferring high-quality grasses.
