The National World War I Memorial is a planned memorial commemorating the service rendered by members of the United States Armed Forces in World War I. The 2015 National Defense Authorization Act established the World War I Centennial Commission, which was given the authority to build the memorial in Pershing Park, located at 14th Street and Pennsylvania Avenue NW in Washington, D.C., in the United States. The park, which has existed since 1981, also contains the John J. Pershing General of the Armies commemorative work.
