The genus '''''Cajanus''''' is a member of the plant family [[Fabaceae]]. There are 37 species, mainly distributed across [[Africa]], [[Asia]] and [[Australasia]].

Species include the [[pigeon pea]] (''C. cajan''), which is a significant food crop.

The natural range of ''Cajanus'' species includes West Africa, Madagascar and the Comoros, the Indian Subcontinent, Indochina, southern China and Taiwan, Malesia, New Guinea, and northern Australia. Typical habitats include seasonally-dry tropical open forest, woodland, and grassland, often in rocky or disturbed areas. Some species, including ''Cajanus cajan'', have been introduced to the tropical Americas, elsewhere in Africa, and to central Asia.<ref name = powo/>

''Cajanus'' species are used as food plants by the [[larva]]e of some [[Lepidoptera]] species including ''[[Endoclita malabaricus]]''.
