The Gelocidae are an extinct family of hornless ruminantia that are estimated to have lived during the Eocene and Oligocene epochs, from 36 MYA to 6 MYA. The family generally includes ruminants with dental traits of both the Tragulina and Pecora, making it a notorious wastebasket taxon with unresolved affinities.

Members of the family Gelocidae were long-legged, even-toed ungulates adapted for running and grazing. The Gelocidae likely share a close common ancestor with Moschidae and were of a similar size and shape. They had similar dentition and proportions to members of Moschidae, but lacked the sabre-like tusks of the modern musk deer.
