The Helaletidae are an extinct family of tapiroid, closely related and likely ancestral to the true tapirs, which contain Protapirus and all descendants.[3] In alternative classifications, Helaletidae is treated as a subfamily within the Tapiridae, the Helaletinae.
Members of the family are defined by having less bilophodont cheek teeth compared to other tapiroids.[4]
