Mary Ada Pickford, CBE (5 July 1884 – 6 March 1934) was an English politician, industrialist and historian. After working to support the Conservative Party over several years, she was elected as a Member of Parliament in 1931, and specialised in Indian issues; she also used her knowledge of the factory system gained while working as an inspector during the First World War to speak about employment issues. Pickford supported her constituency through the depression of the 1930s but died suddenly of pneumonia at the age of 49.
