Howard Walter Cannon (January 26, 1912 – March 5, 2002) was an American politician. He served as a United States Senator from Nevada from 1959 until 1983 as a member of the Democratic Party.
Cannon was born in Saint George, Utah. He attended the Arizona state teacher's college and the University of Arizona law school. He became a lawyer in Arizona, Nevada and Utah, being accepted to the bar in all three states. In World War II he served as a bomber pilot in the United States Army Air Corps and its subsequent incarnation as the United States Army Air Forces. Assigned to the European theater, he was shot down over the Netherlands in September 1944 and spent 42 days trying to return to the Allied lines with the assistance of the Dutch underground. Released from active duty in 1946, he joined the Army Air Forces Reserve until 1947 when he transitioned to the Air Force Reserve concurrent with the establishment of the U.S. Air Force as a separate service. Continuing to fly in the Air Force Reserve, he achieved command pilot status and ultimately retired from the Air Force Reserve with the rank of Major General. His military decorations included the Silver Star, Legion of Merit, Distinguished Flying Cross, the Purple Heart and the Air Medal (3 awards).
In 1949 Cannon was elected city attorney of Las Vegas, Nevada and reelected three times. In 1958 he was elected to the United States Senate.
