Ballusia is an extinct genus of small bear from the Early Miocene epoch, about 20.5-18 million years ago. Fossil remains attributed to the genus have been uncovered in Europe (Poland) and Asia (Russia, Mongolia, China). The genus Ballusia was established in 1998 on the basis of different fossils originally classified as various species of the genera Ursavus and Hemicyon, with B. elmensis as the type species.
