The Business Plot, also called the Wall Street Putsch and The White House Putsch, was a political conspiracy in 1933, in the United States, to overthrow the government of President Franklin D. Roosevelt and install Smedley Butler as dictator. Butler, a retired Marine Corps major general, testified under oath that wealthy businessmen were plotting to create a fascist veterans' organization with him as its leader and use it in a coup d'état to overthrow Roosevelt. In 1934, Butler testified under oath before the United States House of Representatives Special Committee on Un-American Activities on these revelations. Although no one was prosecuted, the congressional committee final report said, "there is no question that these attempts were discussed, were planned, and might have been placed in execution when and if the financial backers deemed it expedient."

Major General Smedley Darlington Butler, nicknamed the Maverick Marine, was a senior United States Marine Corps officer. During his 34-year career, he fought in the Philippine–American War, the Boxer Rebellion, the Mexican Revolution, World War I, and the Banana Wars. At the time of his death, Butler was the most decorated Marine in U.S. history. By the end of his career, Butler had received sixteen medals, including five for heroism; he is the only Marine to be awarded the Brevet Medal as well as two Medals of Honor, all for separate actions.
