Caecobarbus geertsi (African blind barb or Congo blind barb), locally known as barbu aveugle or poisson cavernicole d'Afrique, is a ray-finned fish species in the family Cyprinidae. It is the only member of the monotypic genus Caecobarbus.[2] It is George Albert Boulenger who made the discovery of this fish in 1921.

It is found only in Thysville Caves in the Democratic Republic of the Congo.[1] Like other cavefish, it has no externally visible eyes and reduced pigmentation. Its maximum length is 110 mm (4.3 in). They may live as long as 15 years.[3]

It is threatened by sedimentation.[1] Its trade as aquarium novelty is also a possible threat.[3]
