Sir Alfred Charles Davidson KBE (1882–1952) was an Australian banker and a domineering figure in the 1930s Australian business life. He was best known as the general manager of the Bank of New South Wales from 4 January 1929 (now Westpac Bank), when this bank entered its perhaps most critical periods of existence.^[1] He stayed on at the bank until June 1945 when he was persuaded to retire due to ill health.

Davidson was born on 1 April 1882 in Brisbane, son of bank manager James Madgwick Davidson, and his Queensland-born wife Lucy (née Cribb). He was the grandson of the factory owner and financier turned well-known Queensland humanitarian Alfred Davidson who migrated to Queensland in 1863 and made a name for himself as Queensland's representative of the British Aborigines' Protection Society.
