Frank Plowman Woods (December 11, 1868 – April 25, 1944) was a five-term Republican U.S. Representative from Iowa's 10th congressional district, in north-central Iowa. He reached a House leadership position after only two terms. However, in 1917 his vote against the United States' declaration of war on the German Empire effectively ended his political career, leading to his loss of the Republican nomination for re-election to his seat, and of his leadership position for the remainder of his final term.
