The Carmel-by-the-Sea World War I Memorial Arch is a World War I memorial designed in 1919 by architect Charles Sumner Greene and located at Ocean Avenue and San Carlos Street center median divider in Carmel-by-the-Sea, California.

[1] The Memorial Arch has been a historic landmark since November 1921, when it was built for Carmel World War I veterans.

Fred Sheldon of the Carmel Church and attorney J. H. Andresen spoke at the proceedings at the intersection of Ocean Avenue and San Carlos Street to a reviewing stand of local political and military dignitaries.

Harry J. Downie (1903-1980) donated the first Spanish-style bell, believed to date back to 1692, which was added to the memorial in 1966 to mark the city's 50th anniversary.

[10][4] The Memorial Arch is significant under California Register criteria in history as a community’s expression of respect for 56 Carmelites who served their county in World War I.
