Austroraptor is an extinct genus of paravian theropod dinosaur that lived during the Maastrichtian age of the Late Cretaceous in what is now Argentina. It is commonly considered to be a Dromaeosaurid, but some studies place it in the proposed family Unenlagiidae.

Austroraptor was a large, moderately-built, ground-dwelling, bipedal carnivore, estimated at 5-6 meters (16-20 feet) long. It is one of the largest dromaeosaurids known, with only Achillobator, Dakotaraptor, and Utahraptor approaching or surpassing it in length.

It is theorized that Austroraptor and its relatives preyed on fish due to the shape of their teeth.
