Bicentenaria is a genus of carnivorous coelurosaurian theropods which lived during the early Late Cretaceous (about 90 million years ago) in what is now Argentina. It currently contains only the type species, Bicentenaria argentina. Estimates suggest that it was 2.5 to 3 metres (8 to 10 ft) in length. This name was first reported in news articles in June 2012, and the paper describing it was formally published in August 2012.
