Acheroraptor is an extinct genus of dromaeosaurid theropod dinosaur known from the latest Maastrichtian Hell Creek Formation of Montana, United States. It contains a single species, Acheroraptor temertyorum. A. temertyorum is one of the two geologically youngest known species of dromaeosaurids, the other being the possibly dubious Dakotaraptor steini, which is also known from the same formation. A basal cousin of Velociraptor, Acheroraptor is known from upper and lower jaw material.
