Hemicyoninae is an extinct subfamily of Ursidae,^[2][1] often called dog bears (literally "half dog" (Greek: ἡμικυων hemi-kyōn)). They were bear-like carnivorans living in Europe, North America, Africa and Asia during the Oligocene through Miocene epochs 33.9–5.3 Ma, existing for approximately 28.6 million years. They are sometimes classified as a separate family.^[3]

The hemicyonines consists of three tribes: the Cephalogalini, Phoberocyonini, and Hemicyonini. In the past the hemicyonines were evaluated into family level (Hemicyonidae).^[3] However the vast majority of papers and researchers that cover the evolution of bears often classified them as an extinct subfamily of ursids or stem-bears.^[4][5] The genus Agriotherium was once classified as a hemicyonine^[3] but recent work has shown the genus is a crown-ursid.^[6]
