James W. Good (September 24, 1866 November 18, 1929) was an American politician from the state of Iowa. He was a member of the United States Republican Party. Good was born near Cedar Rapids, Iowa and was a lawyer before entering politics. He was a member of the United States House of Representatives from 1909 to 1921, and was chairman of the House Appropriations Committee from 1917 to 1921. He was reelected to a seventh term in Congress in 1920, but resigned in June 1921. He practiced law in Chicago, Illinois. In 1928 he worked to elect Herbert Hoover, a fellow Iowa Republican, as President of the United States. When Hoover took office in March 1929, he appointed Good to be the United States Secretary of War and Good was soon confirmed by the Senate. He served in that position for eight months, until his sudden death. He died in Washington, D.C. shortly after the stock market crash which caused the Great Depression.
