Patria (pronounced PAY-tree-uh, as in patriot) is a 1917 15-chapter American serial film starring Irene Castle, Milton Sills, and Warner Oland, based on the novel The Last of the Fighting Channings by Louis Joseph Vance. Patria was an independent film serial funded by William Randolph Hearst in the lead-up to the United States' entry into World War I. The film in its original form contained anti-Japanese propaganda and was investigated by a Senate committee. The Argentine title for the film was La Heroina de Nueva York. At least several fragments of the film survive.
