Air Vice Marshal Harold Spencer Kerby, CB, DSC, AFC (14 May 1893 – 8 June 1963) was Canadian-born air officer of the Royal Air Force. He served in the Royal Naval Air Service during the First World War, where he became a flying ace with nine confirmed aerial victories, later transferring to the Royal Air Force, rising to command of British Air Forces in East Africa during the Second World War.

Kerby was born in Hamilton, Ontario, Canada, the only son of Reverend George William Kerby, and his wife Emily (née Spencer). In 1903 the family moved to Calgary, Alberta, where his father served as minister at the Central Methodist Church, and then as principal of Mount Royal College from 1911. His mother was a teacher, author, feminist, and social activist, who served as first president of the Calgary Young Women's Christian Association, first vice-president of the Calgary Local Council of Women, and who eventually became vice-president of the National Council of Women of Canada. Harold Kerby graduated from the University of Toronto with a degree in mechanical engineering.

Kerby joined the Royal Naval Air Service in February 1915 as a probationary flight sub-lieutenant, being confirmed in his rank on 21 March. He was granted Royal Aero Club Aviators Certificate No. 1214 after soloing a Grahame-White biplane at the Grahame-White School at Hendon on 5 May.
