Ruxton and Riderwood are unincorporated communities in Baltimore County, Maryland. They are sometimes considered a part of Towson and are part of Towson's census area. The boundaries of Ruxton have been established largely by local custom. Both the eastern boundary, Charles Street, and the western, Falls Road, are generally agreed upon. The northern and southern boundaries are somewhat imprecise. To the northeast, Ruxton and neighboring Riderwood are bounded by the Baltimore Beltway (I-695); to the northwest, affiliation with Ruxton follows West Joppa Road, the Old Court Road extension alongside the Baltimore-Harrisburg Expressway (I-83), and finally Ruxton Road to the intersection with Falls. A southern boundary can be discerned by drawing a crude line from the southerly intersection of Bellona Avenue and Charles to the intersection of WestLake Avenue and Falls.
Ruxton takes its name from Nicholas Ruxton Moore, a captain and commander of the Baltimore Light Dragoons during the American Revolution War. He also participated in suppressing the Whiskey Rebellion in 1794, the same year he purchased the land that would become Ruxton. Ruxton was once the location of the country estates of Baltimore's wealthy landed gentry. Though the area became suburbanized during the course of the twentieth century, Ruxton is still considered one of the premier neighborhoods in the Baltimore area, along with Roland Park, Homeland, Guilford and the Falls Road corridor. Many of the original estates still remain, though there have been many new homes built between them.
