Greer Mill, also known as Greer Roller Mill, is a historic grist mill located near Alton, Oregon County, Missouri. It was built in 1899, and is a 2 1/2-story, rectangular, frame mill building on a sandstone foundation. It has a side gable roof topped by a cupola. The mill operated until 1920. Conservationist Leo Drey purchased the property in 1987, and later sold it to the Forest Service for incorporation into the Eleven Point District of the Mark Twain National Forest.{{cite web| url =http://dnr.mo.gov/shpo/nps-nr/05001551.pdf| title = National Register of Historic Places Inventory Nomination Form: Greer Mill | accessdate = 2017-01-01| author=Kim Leazenby, Pamela Watson, & Bonnie Stepenoff|format = PDF| date=May 2004|publisher=Missouri Department of Natural Resources}} (includes 4 photographs from 2004){{rp|5, 12}}
