The Infamy Speech was a speech delivered by United States President Franklin D. Roosevelt to a Joint Session of the U.S. Congress on December 8, 1941, one day after the Empire of Japan's attack on the U.S. naval base at Pearl Harbor, Hawaii, and the Japanese declaration of war on the United States and the British Empire. The name derives from the first line of the speech: Roosevelt describing the previous day as "a date which will live in infamy". The speech is also commonly referred to as the "Pearl Harbor Speech".
