General George Rust (1788–1857) was a general in the U.S. Army in the early 19th century and a prominent landowner in Loudoun County, Virginia. Rust was involved in the defense of Baltimore during the War of 1812 and was a member of the Virginia House of Delegates in 1818-1819 and 1820-1823. Rust built Rockland near Leesburg, Virginia about 1822, which is listed on the National Register of Historic Places and which remains in the hands of Rust family descendants. Rust also owned Exeter, a nearby plantation. Rust's son was Colonel Armistead Thomson Mason Rust (1820–1887), a West Point graduate who fought with the Confederate 19th Virginia Infantry during the American Civil War.
