David Crowder Waybur (1919 – March 28, 1945) was a United States Army officer and a recipient of the United States military's highest decoration—the Medal of Honor—for his actions in World War II. During the Allied invasion of Sicily, he led his small patrol in its defense against an attack by four Italian tanks. Despite being seriously wounded, he continued to lead and personally disabled one tank with only a Tommy gun. After receiving the Medal of Honor for these actions, he returned to combat and was killed in action in Germany.
