Choyrodon is a genus of hadrosauroid dinosaur from the Early Cretaceous (Albian) Khuren Dukh Formation of Mongolia. The type and only species is Choyrodon barsboldi. The generic name is derived from the city of Choyr, and -odon, from Latin for tooth; the specific name barsboldi honours paleontologist Rinchen Barsbold. The material consists of a holotype partial skull and cervical ribs, with two other partial skulls both with associated postcranial material. It was found to be the sister taxon of Eolambia.

==History and naming== Three specimens of a new iguanodontian were discovered in the Khuren Dukh Formation of Mongolia by an expedition led by Mongolian paleontologist Rinchen Barsbold. These three specimens, stored in the Mongolian Natural History Museum, were found within the same sediments that had yielded the iguanodontian Altirhinus, but comparisons showed that they represented different taxa and so in 2018 American paleontologist Terry Gates and colleagues named them Choyrodon barsboldi. The genus name is derived from the nearby city of Choyr and the Latin word for "tooth", don, while the species name is in honour of Barsbold and his contributions to Mongolian paleontology.
