Schleitheimia schutzi (named after the type locality of Schleitheim), is an extinct genus of sauropodiform sauropodomorph]] dinosaur that lived in Switzerland during the Late Triassic period. It was found in the Gruhalde Member of Klettgau Formation of northern Switzerland.

The type material was collected between 1952 and 1954 by Emil Schutz. They were donated to the University of Zürich in 1955. In 1986, most of the material was described by Peter Galton, who referred them all to the species Plateosaurus engelhardti.

In 2020, Oliver Rauhut, Femke Holwerda and Heinz Furrer redescribed most of Schutz's remains, as well as some remains in the collections of the Museum zu Allerheiligen in Schaffhausen and new remains from a excavation in 2016 led by Holwerda. They found that the earlier found remains represented a new genus and species, which they named Schleitheimia schultzi, honoring the type locality and the discoverer of the type remains. The 2016 finds were not referred. Finds made by Schultz near Hallau-Schwärzibuck were considered to represent a different new taxon and remained unnamed.

The holotype, PIMUZ A/III 50, was found in a layer of the Klettgau Formation dating from the Norian. It consists of a partial right ilium. Several other bones from the general locality were designated as paratypes. Because they are consistent in morphology, the describers referred all of them to the same taxon, if not the same individual.

Schleitheimia's holotype shows a unique combination of traits that in themselves are not unique. There is a broad, rounded ridge on the iliac blade that ends in a large, rounded expansion on the ilium. The fourth tronchanter of the ilium is very robust. The crista tibiofibularis of the femur is broad and there is no posteriorly facing shelf is present lateral to the crista.
