Parvosuchus (meaning "small crocodile") is an extinct genus of gracilisuchid pseudosuchians from the Middle–Late Triassic Santa Maria Formation (Paraná Basin) of Brazil.

The Parvosuchus holotype specimen, CAPPA/UFSM 0412, was discovered at the Linha Várzea 2 site in the Pinheiros-Chiniquá Sequence, which belongs to the Santa Maria Formation of the Santa Maria Supersequence (Paraná Basin) in Paraíso do Sul municipality of Rio Grande do Sul state, Brazil.

The specimen consists of a largely articulated skeleton, including the skull and lower jaws, the last 11 dorsal vertebrae, two sacral vertebrae, a pelvic girdle, part of the right femur, and a partial left hindlimb (comprising pieces of the femur, tibia, fibula, and calcaneum).

[1] In 2024, Rodrigo T. Müller described Parvosuchus aurelioi as a new genus and species of gracilisuchid pseudosuchians based on these fossil remains.

[1] In his phylogenetic analyses, Müller (2024) recovered Parvosuchus in a clade with Maehary (which was originally identified as an early pterosauromorph[3]) and Gracilisuchus within the Gracilisuchidae.
