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.
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.
[1] Stehlin is commemorated in the scientific name of a species of lizard, Gallotia stehlini.
