Hans Georg Stehlin (1870–1941) was a Swiss paleontologist and geologist.

Stehlin specialized in vertebrate paleontology, particularly the study of Cenozoic mammals. He published numerous scientific papers on primates and ungulates. He was president of the commission of the Natural History Museum of Basel.

In 1910 Stehlin coined the term Grande Coupure to refer to the extinction event which occurred 33.9 millions of years ago, which defines the Eocene-Oligocene limit. It originated a huge change in organisms, especially the mammals of Europe.{{cite journal| author = Stehlin, H.G.| title = Remarques sur les faunules de Mammifères des couches eocenes et oligocenes du Bassin de Paris | year = 1910| journal = Bulletin de la Société Géologique de France| volume = 4| number = 9| pages = 488–520}} (in French).
