This is a list of notable people who served as ambulance drivers during the First World War. A remarkable number—writers especially—volunteered as ambulance drivers for the Allied Powers. In many cases, they sympathized strongly with the ideals of the Allied Powers, but did not want, or were too young or old, to participate in a combat role. For women, combat was not an option at the time. Several of the Americans on the list volunteered before the United States' 1917 entry into the war. Many of the American writers would later be associated with the Lost Generation.
