Several ships, buildings, and monuments have been dedicated to Munro, and a street in his hometown is named after him in his honor. The anniversary of his death is annually observed in Cle Elum and at Coast Guard Training Center Cape May. His grave has been designated a historical site by Washington state. He is the namesake of the "Douglas Munro March", the Navy League's Douglas A. Munro Award, the Coast Guard Foundation's Douglas Munro Scholarship Fund, and the Veterans of Foreign Wars' Douglas Munro-Robert H. Brooks Post. He is the only non-Marine to have his name enshrined on the Wall of Heroes of the National Museum of the Marine Corps.
