Leigh Noyes (December 15, 1885 – March 24, 1961) was a vice admiral in the United States Navy during World War II.

At the time war broke out in 1941, Rear Admiral Noyes was director of naval communications in Washington and was accused of not passing along the "Bomb Plot" intercept of 9 October 1941 indicating that the Japanese Consulate in Honolulu was under instructions to report ship locations in Pearl Harbor.

In March 1942, he was sent to Pearl Harbor servicing as Admiral Halsey's shore administrator.

He was considered to replace Halsey for Midway but instead Admiral Raymond A. Spruance was selected.

After Wasp was torpedoed on September 14, 1942, he was criticized for his actions and reassigned as commander, Naval Air Force, Pacific Fleet, which he held until October 1942.
