Austrocheirus is an extinct genus of theropod dinosaur that lived during the Late Cretaceous period.

[1] The fossils were found on 17 March 2002 in the Pari Aike Formation, dating from the Campanian to Maastrichtian.

[4][5] A cladistic analysis indicated Austrocheirus had a basal position in the Abelisauroidea, but was more derived than Ceratosaurus and Berberosaurus.

[6] A partial ulna, manual claw and metatarsal that belongs to the holotype of Austrocheirus further supports Rauhut's argument, with the important morphological differences preventing its classification to a particular clade of theropods; for this reason, the authors suggested that it is best to classify this genus under incertae sedis Averostra, before more materials are discovered.

Their results are displayed in the cladogram below:[7] Kryptops (postcranium) Elaphrosaurinae Ceratosauridae Berberosaurus Eoabelisaurus Ligabueino Berthasaura Afromimus Austrocheirus Noasauridae Abelisauridae
