Aulonocara is a genus of haplochromine cichlids endemic to Lake Malawi in East Africa. All Aulonocara species are maternal mouth brooders. Particularly in the aquarium hobby, Aulonocara species are also known as peacock cichlids, aulonocaras or simply "peacocks". This genus is strongly sexually dichromic, even by haplochromine standards.

As aquarium fish, they are best kept with other medium-sized nonaggressive cichlids from Lake Malawi. All peacock cichlids are known to be less aggressive than their Mbuna counterparts, and thrive in warmer waters that have a slightly basic pH.
