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.

Spies from Japan conspire to steal the Channing "preparedness" fortune and invade the United States, beginning in New York, then allying themselves with Mexicans across the border.

A German propagandist, whose articles had appeared in Hearst newspapers, had written a letter to Franz von Papen explaining the scheme to use a motion picture to deprecate Japan.

"[2] Literary critic Edward Wagenknecht commented: The year 1916 produced the most vicious of all serials, Hearst’s Patria, written by Louis Joseph Vance and starring Irene Castle, which whipped up war fever, glorified the munitions makers, and so openly attacked Japan that President Wilson personally requested that it be withdrawn.
