thumb|left|Life restoration of Hupehsuchus nanchangensis Hupehsuchus is an extinct genus of small marine reptiles, about 1 m (3 ft) long, found in the area of Hubei in China. This marine reptile lived in the Olenekian stage of the Early Triassic period.

Hupehsuchia is an order of diapsid reptiles closely related to ichthyosaurs. The group was short-lasting, with a temporal range restricted to the late Olenekian age, spanning only a few million years of the Early Triassic. The order gets its name from Hubei Province, China, from which many specimens have been found. They are probable members of the clade Ichthyosauromorpha.

Nanchangosaurus is an extinct genus of aquatic reptiles native to the middle Triassic of China. It was named after the area in China, Nanchang, where it was found. It was about more than in length, and probably fed on fish or used its long jaws to probe for aquatic invertebrates. It resembled the ichthyosaurs in build, and may be related to them.

Parahupehsuchus is an extinct genus of hupehsuchian marine reptiles from the Early Triassic of China. The genus is monotypic, known from the single species Parahupehsuchus longus and based on a single specimen. Like other hupehsuchians, it had an elongated torso, a tail nearly as long as the rest of the body, short and paddle-like limbs, extra bones in the fore- and hind limbs, thick ribs and gastralia, neural spines of the vertebrae split into two parts, and bony plates over the neural spines. It differs from other hupehsuchians in having an even more elongated body and wider ribs that touch

Eohupehsuchus is a genus of extinct aquatic diapsid from the Upper Spathian (latest Early Triassic) of Hubei Province, located in Central China. The genus is monotypic and belongs to the order Hupehsuchia, whose members are characterized by toothless beak-like snouts, a row of dermal plates along their backs, and aquatic adaptations including paddle-shaped limbs and fusiform bodies with pachyostotic ribs.

Baisesaurus (meaning "Baise lizard") is an extinct genus of ichthyosauromorph reptiles from the early Triassic (Spathian age) Luolou Formation of Guangxi, China. The genus contains a single species, Baisesaurus robustus, known from a partial postcranial skeleton.
