Birbalomys is an extinct genus of rodent from Asia.

The 30 cm (12 in)-long creature has been thought to have been a member of the extant gundi family, but reconstructions of its physical appearance are speculative. Birbalomys bear resemblance with the Ctenodactyloidea, Chapattimyidae, and Yuomyidae families.^[1] Early findings suggest that Birbalomys were found in the Subathu Formation in the Kunhar River in the Eocene epoch.^[2]
