Trogosus is an extinct genus of tillodont mammal. Fossils have been found in Wyoming and British Columbia, and date from the Eocene between 54.8 to 33.7 million years ago.

Trogosus was a bear-like herbivore with a large, short skull and flat feet, and had a skull 35 cm (14 in) long with an estimated body weight of 150 kg (330 lb). It had large, rodent-like incisors, which continued growing throughout the creature's life. Judging from the heavily worn molar teeth, Trogosus fed on rough plant material, such as roots and tubers.
