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.

[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.

Still, they recovered it in a clade also including Berthasaura and Afromimus in their phylogenetic analysis, which they named Berthasauridae.

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