William Keil (March 6, 1812 – December 30, 1877) was the founder of communal religious societies in Bethel, Missouri, and Aurora Colony in Oregon, that he established and led in the nineteenth century. Influenced by German Lutheranism, pietism, and revival Methodism, Keil's theology was based on the principle of the Golden Rule as well as the view that people should try to share all with others by living communally (Acts 4:32-37). His house near Bethel, known as Elim, was listed on the National Register of Historic Places in 1971. Located nearby is Hebron.
