James William Good (September 24, 1866 – November 18, 1929) was an American politician and lawyer from the state of Iowa, who served in the U.S. House of Representatives and the Cabinet of President Herbert Hoover as Secretary of War.

But soon after his fellow Republican, Warren G. Harding, was elected president in November 1920, Good disclosed that he would likely resign his seat in Congress and join a Chicago, Illinois, law firm, once Good's plan to reorganize the budgetary process was adopted.

[4] Republican Cyrenus Cole of Cedar Rapids won a special election to fill his vacancy, and was sworn on August 1, 1921.

In 1928 Good worked to elect Herbert Hoover, a fellow Iowa Republican, as President of the United States.

He died in Washington, D.C., on November 18, 1929, shortly after the Wall Street crash of 1929, at the beginning of the Great Depression.
