Massaliasuchus is an extinct monospecific genus of allodaposuchid eusuchian crocodyliform from the Late Cretaceous (Santonian–Campanian) Fuvelian Lignites of southeastern France.

Massaliasuchus was first described in 1869 by Philippe Matheron as Crocodilus affuvelensis, based on remains including skull bones.

[1] Recent cladistic analysis places Massaliasuchus as a member of Allodaposuchidae, a clade of basal eusuchians from the Late Cretaceous of southern Europe.

[3] The genus can be distinguished from Musturzabalsuchus in having 15 alveoli in the dentary.

[4] However, Massaliasuchus is usually omitted from phylogenetic analyses since it is only represented by poorly-preserved material.
