The Malvern Roller Mill, also known as Appel Mill and Malvern Milling Company, is a 19th-century grist mill located near the unincorporated village of Malvern, Illinois, in rural Whiteside County, north of Morrison, Illinois, United States. The original mill on the site, built by 1853, was destroyed by a flood and the present mill was erected in 1858. The mill's first owner was William P. Hiddleson who operated the mill until he sold to Benjamin Hough in 1871. The mill changed hands over the years until it landed under the control of George Appel in 1892. The Appel family closed the mill in 1942 but it remained in their family until 1985. The Malvern Roller Mill was added to the U.S. National Register of Historic Places in 1995.
