Thomas Falcon Hazell & Bar (7 August 1892 – 4 September 1946) was a fighter pilot with the Royal Flying Corps, and later, the Royal Air Force during the First World War.
Hazell scored 43 victories in 1917–18 making him the fifth most successful British "flying ace" of the war, and the third most successful Irish-born pilot, behind Edward Mannock and George McElroy, as well the only pilot to survive the war from both groups.
