"Mandasuchus" is an extinct genus of prestosuchid rauisuchian that is yet to be formally described. Thus, the name is considered a nomen nudum. Fossils have been found from the Manda Formation of Tanzania and date back to the Ladinian or Anisian stage of the Middle Triassic. The name was first used in a 1957 doctoral dissertation by Alan J. Charig of the University of Cambridge along with "Teleocrater", another nomen nudum then considered to be a dinosaur. Several well preserved specimens have been found, although there is little cranial material.
