The Friendly Isles is a 1928 American novel written by Calvin Coolidge. Set during the then-ongoing Pacific War, the novel concerned the misadventures of three American sailors aboard the fictional USS Roanoke in the Samoan Islands. A mix of social commentary and dark humor, the novel gained traction due to strong anti-war sentiment in the United States at the time and was criticized from both ends of the political and literary spectrum for being distasteful, unpatriotic (especially since Coolidge was the former Vice President of the United States), obscene and "un-American," while also being praised for being a bold story and a damning glance at the conflict in the Pacific.
