Tatankaceratops (meaning "bison horned face") is a controversial genus of herbivorous chasmosaurine ceratopsid dinosaur that lived during the Late Cretaceous period (latest Maastrichtian stage, about 66 million years ago) in what is now the upper Hell Creek Formation, in South Dakota. It is known from a single partial skull housed at the Black Hills Institute, BHI 6226, described by Christopher J. Ott and Peter L. Larson in 2010 as the type species Tatankaceratops sacrisonorum
