Rapator is a genus of theropod dinosaur from the Griman Creek Formation of New South Wales, Australia, dating to the Cenomanian age[1] of the Cretaceous period.

[3] The holotype and only known specimen, BMNH R3718, consists of a single left hand bone, discovered around 1905 near Wollaston, on Lightning Ridge.

[3] This manual element shows a prominent dorsomedial process, a feature shared with the much smaller Ornitholestes which occasioned the specific name.

If Rapator had a build like Australovenator, it would have attained a considerable size: a body length of nine metres (30 ft) has been estimated.

[4] The type specimen of Rapator was originally described as a metacarpal I, a bone from the upper part of a theropod's hand.
