Oblitosaurus (meaning "forgotten lizard") is a genus of ankylopollexian ornithopod dinosaur from the Late Jurassic Villar del Arzobispo Formation of Spain.

[1] The skeletal remains were identified as belonging to a new genus and species of ornithopod, Oblitosaurus bunnueli, in 2023.

[1] Oblitosaurus has been estimated as being 6–7 metres (20–23 ft) long, larger than its close relatives Camptosaurus and Draconyx.

Furthermore, their analysis also supports a monophyly of Camptosaurus, showing for the first time all the species assigned to it in a single clade.
