Santanaraptor (meaning "Santana Formation thief") is a genus of tyrannosauroid theropod dinosaur that lived in South America during the Early Cretaceous (late Aptian-early Albian), about 112 million years ago.

[1] The species epithet refers to Placido Cidade Nuvens [pt], who founded the Museu de Paleontologia da Universidade Regional do Cariri.

The holotype (MN 4802-V) is a juvenile partial skeleton consisting of three caudal vertebrae with chevrons, ischia, femora, tibia, fibula, pes, and soft tissue.

[4] While primarily known from hindquarter elements, the individual represented by the fossil may have reached 1.5 metres (4.9 ft) in length and 15 kilograms (33 lb) in mass.

[7] However, this position has been criticised, as the supposed tyrannosauroid characters are widely distributed in Coelurosauria, and several aspects of the foot are more similar to noasaurids.
