William Eric Aalto (born William Oliver Ahlström, July 30, 1915 – June 11, 1958) was an American soldier and member of Abraham Lincoln Battalion, a unit that volunteered to fight during the Spanish Civil War for the Popular Front. During his time in Spain, Aalto wrote: "A soldier who is politically conscious that he is right and who has a feeling of community with his society... will do his job well."Toward the end of his life, he was poet James Schuyler's lover, and features in the latter's poem Dining Out with Doug and Frank.
