Ruehleia is a sauropodomorph dinosaur genus that thrived during the Late Triassic period in Germany. The type species, R. bedheimensis, was officially described by Galton in 2001 and is named in honor of the German paleontologist Hugo Rühle von Lilienstern. Discovered back in 1952, the holotype encompasses a nearly complete skeleton, featuring cervical (neck), dorsal (back), and caudal (tail) vertebrae, a partial sacrum, a scapulocoracoid, pelvic bones, most of the limb bones, and partially complete manus (hands). These fossils were unearthed in central Germany and date back to the Norian stage, which spans approximately 216 to 208 million years ago.

Ruehleia belongs to the sauropodomorph group of dinosaurs, which served as the ancestors of the colossal quadrupedal sauropods that later emerged and diversified during the Jurassic period. As a prosauropod, Ruehleia retained the ability to move primarily on its hind legs, although it is plausible that it dropped onto all fours while feeding or drinking. The holotype of Ruehleia was retrieved from the Trossingen Formation in Germany, typically associated with the late Norian period, although it slightly overlaps with the early Rhaetian stage.
