The Newark Canyon Formation is a Mesozoic geologic formation in Nevada in the United States.
Dinosaur remains have been recovered from the formation, although none have yet been referred to a specific genus. These include a non-ankylosaurid ankylosaur (possibly nodosaurid), a non-hadrosaurid ornithopod, a primitive neoceratopsian, and a tyrannosauroid, all represented by teeth. Other dinosaur specimens are known but cannot be assigned to any specific clades due to their non-diagnostic nature.
