Continuoolithus is an oogenus (fossil egg genus) of dinosaur egg found in the late Cretaceous of North America. It is most commonly known from the late Campanian of Alberta and Montana, but specimens have also been found dating to the older Santonian and the younger Maastrichtian. It was laid by an unknown type of theropod. These small eggs (measuring 77–123 mm (3.0–4.8 in) long) are similar to the eggs of oviraptorid dinosaurs (oofamily Elongatoolithidae), but have a distinctive type of ornamentation.
