Albertavenator (meaning "Alberta hunter") is a genus of small troodontid theropod dinosaur, known from the early Maastrichtian in the Cretaceous period. It contains a single species, A. curriei, named after paleontologist Phil Currie, based on a partial left frontal found in the Horseshoe Canyon Formation of Alberta during the 1990s. Albertavenator's discovery indicates that small dinosaur diversity may be underestimated at present due to the difficulty in identifying species from fragmentary remains.
