Rodolphoolithus is an oogenus of elongatoolithid egg native to the Irbzer Formation of Morocco.

It is known only from a single partial egg and several eggshell fragments, but it probably had a highly elongated shape like other Elongatoolithids.

The ornamentation of its outer surface is ramotuberculate, i.e. covered with low, irregular ridges.

The pore system cannot be observed due to recrystallization of the fossilized eggshell.

Like other Elongatoolithids, Rodolphoolithus was laid by small theropods.
