Thomas A. Greene Memorial Museum, also known as Greene Geological Museum or Greene Museum, is a mineral and fossil museum in Milwaukee, Wisconsin administered by the Department of Geosciences at the University of Wisconsin–Milwaukee. The current curator is Dr. Stephen Q. Dornbos, a paleontologist and Associate Professor of Geosciences at UWM.
The original fireproof museum building, designed by noted Milwaukee architect, Alexander Eschweiler, held the collection of Thomas A. Greene, an amateur geologist. In 1913, Greene's heirs, Mrs. H.A.J. Upham and Mr. Howard Greene, had the facility built to house his collection, and it was declared a National Historic Landmark in 1993. The collection has been removed from the building, and is now displayed and housed in Lapham Hall on the UWM campus.
Greene amassed most of the fossils in his collection, totaling about 75,000 specimens, during the 1880s and 1890s. The majority of these specimens come from the Silurian Niagara Formation and the Devonian Hamilton Formation in the vicinity of southeastern Wisconsin.
