Aspalathus obliqua is a species of plant in the family Fabaceae endemic to the Kouebokkeveld Mountains in the Northern Cape, South Africa. It is threatened with extinction.
Aspalathus obliqua is found in Bokkeveld Sandstone fynbos habitat, on deep sandy flats.
Aspalathus obliqua has been classified as Vulnerable due to its restricted range of less than 10km<sup>2</sup>; known from only a single location. As an obligate seeder, the lack of regular fire due to rooibos tea farming and livestock grazing, is an added threat to its survival.
