'''Nautilitoidea''' is a superorder of [[Nautiloidea|nautiloid]] cephalopods, proposed by May Wade, 1988, that comprises the [[Tarphycerida]], [[Oncocerida]], and [[Nautilida]].  The  Nautilitoidea has its origin in the [[Ellesmerocerida|ellesmerocerid]] Bassleroceratidae, sometimes included in the Tarphycerida instead.

The Natilitoidea are united phylogenetically and share characters of being generally exograstric or coiled.  They include the only coiled nautiloids, unless the [[Lituitidae]] actually do belong in the [[Orthocerida]].
