Sir Alfred Charles Davidson (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.
He was the grandson of the factory owner and financier turned well-known Queensland humanitarian Alfred Davidson (1812-1881) who migrated to Queensland in 1863 and made a name for himself as Queensland's representative of the British Aborigines' Protection Society.
