Lieutenant Alfred Stanley Mills (born 26 June 1899 – date of death unknown) was a World War I flying ace credited with 15 aerial victories. Mills graduated from Campbell College, Belfast before joining the service. In 1916, he was received at Somerville Hospital in Oxford. After being assigned to No. 20 Squadron RAF as an observer gunner, he won his first dogfight by setting afire a Fokker Dr.I on 9 May 1918. In the end of May, he had eight wins to his credit. On 2 July he was awarded the Distinguished Flying Cross. He tallied only a single kill in July, on the 24th. His last six victories came in September 1918. In summary, only three of his victories were the "soft" out of control sort, and all but two were over enemy fighter aircraft.
