Teratodontinae ("monstrous teeth") is a subfamily of extinct hyaenodonts.

Fossil remains of these mammals are known from Middle Eocene to Late Miocene deposits in Africa, the Arabian Peninsula, and Asia.

[2] The name of the subfamily translates as "monstrous teeth" (from Ancient Greek τέρας (téras) 'monster', from Ancient Greek ὀδών (odon) 'tooth' and taxonomic suffix "-inae".
