The La Quinta Formation is a Mesozoic geologic formation which crops out in the Cordillera de Mérida and Serranía del Perijá, Venezuela. At its type locality near La Grita, it consists of a basal dacitic tuff followed by interlayered sandstones, tuffs, siltstones and rare limestones.Dinosaur remains including Laquintasaura and Tachiraptor, are among the fossils that have been recovered from the formation.

Fossil associations suggest that the La Quinta Formation is of Early - Middle Jurassic age.
