Notoglanidium depierrei is a species of catfish (order Siluriformes) family Claroteidae. This species is endemic to Cameroon where it is known only from its type locality of the Sanaga River Basin. It reaches a length of about 17.2 centimetres (6.8 in) SL. It was formerly considered to be the sole member of the monotypic genus Platyglanis but this has now been synonymised with Notoglanidium.
