Karamuru is a genus of prestosuchid archosaur from the Middle Triassic-age Santa Maria Formation of Brazil. It was found in the Paleorrota geopark. It is based on remains that had been assigned to Prestosuchus chininiquensis, including a nearly complete skull. There is some uncertainty about the publication date and authors; as noted by Langer et al. (2007), Kischlat (2000) records it as having been published by Kischlat and Barberena, with no year given.[2] Later, Schultz and Langer considered it to be a junior synonym of Prestosuchus.[3]

Karamuru would have been a carnivorous animal, perhaps 7 meters (23 feet) long and weighing 700 kilograms (1,500 pounds).[4]

Its name relates to the story of Diogo Álvares Correia, a settler called the "Caramuru" by the Tupinambá tribe.
