With 5,000+ residents, Lyon Park is a unique and diverse community.

Learn about the history of our 100+ year old neighborhood.

Welcome to Lyon Park! Established in 1919, Lyon Park is one of the original Arlington neighborhoods and features homes spanning over 100 years, scenic parks, and playgrounds, and welcoming community events associated with our recently renovated community center. Located a short distance from the Metro’s Orange and Silver lines, Lyon Park retains its neighborhood feel, while situated near the urban corridor of Clarendon’s retail stores, bars, and restaurants. [Read 2021 story on Lyon Park from The Washington Post.] The Lyon Park Citizens Association is a resident volunteer body that oversees management of the neighborhood’s private park, county government interactions, and enabling conversations among citizens about neighborhood issues.
