Teihivenator ("strong hunter") is a genus of tyrannosauroid coelurosaur from the Navesink Formation of New Jersey. It contains a single species, T. macropus.

The species was originally classified as a species of Dryptosaurus (= "Laelaps", a name preoccupied by a mite). It was made a separate genus in 2017, by Yun Changyu.[1]

In 2017, preprint paper by Chase Doran Brownstein concluded that the remains of T. macropus are a mixture of non-diagnostic tyrannosauroid and ornithomimid elements, rendering the species a chimera and a nomen dubium.[2] In 2018, Brownstein stated that an originally about two foot long tibia, specimen AMNH FARB 2550, represented a tyranosauroid that probably was distinct from Dryptosaurus, but not sufficiently to base a taxon on.[3]
