Albertonykus (meaning " Alberta claw") is a genus of alvarezsaurid dinosaur from Maastrichtian-age ( Upper Cretaceous) rocks of the Horseshoe Canyon Formation of Alberta, Canada. It is known from forelimb and hindlimb remains from multiple individuals. All but two of the specimens come from a bonebed dominated by Albertosaurus. This bonebed is located at the top of Unit 4 of the Horseshoe Canyon Formation, which dates to about 68.5 million years ago. Albertonykus is interpreted as having fed on wood-nesting termites because the forelimbs appear to be specialized for digging, but are too short for burrowing. Albertonykus is the earliest-known North American alvarezsaurid; isolated remains of alvarezsaurids are known from later rock units in Montana and Wyoming ( USA).
The type species is A. borealis, described by Nicholas Longrich and Philip Currie in a paper published in 2009 (which was available online as a preprint in 2008). The specific name (borealis) means "north".
