Jakapil (meaning "shield bearer" in Puelchean) is a genus of basal thyreophoran dinosaur from the Candeleros Formation of Argentina.

[1] The holotype, MPCA-PV-630, is a partial skeleton including several osteoderms and a complete lower jaw, which were found on land owned by the Mariluan family in 2012 and excavated between 2014 and 2019/2020.

The premaxilla of Jakapil had no teeth, a feature not known in any thyreophoran, while the shape and depth of the dentary are more similar to those of basal neoceratopsians.

[3] In their 2024 analyses, Fonseca and colleagues recovered Jakapil as either the sister taxon to Eurypoda or as the basalmost member of Ankylosauria.

[1] Other animals from this formation include the rhynchocephalians Tika and Priosphenodon, the snake Najash, the mammal Cronopio dentiacutus, the theropods Alnashetri, Buitreraptor, Ekrixinatosaurus, and Giganotosaurus, as well as the sauropods Andesaurus and Limaysaurus.
