Melanopsis magnifica is a species of freshwater gastropod endemic to oases and wadis in Morocco.

Melanopsis magnifica exists mainly (though not exclusively) in shallow streams with stony substrates.

It occurs in several localities, only three of which are recognized by the IUCN: Berkane, Fez, and Ouadi Korifla in Morocco.

It also occurs in Ain Chkef, Agourai, Oued Boufakrane, Ain Chair, Ras Kebdana, Meknes, etc.

Known M. magnifica populations are close to urban areas and are prone to population impacts as a result of pollution and habitat modification.
