Pamela Hansford Johnson, Baroness Snow (May 29, 1912 – June 18, 1981) was an English novelist, playwright, poet, and literary and social critic.  Born in London, Johnson attended Clapham County Girls Grammar School, where she excelled at English, art history, and drama. After leaving school at the age of 16, she took a secretarial course and later worked for several years at the Central Hanover Bank and Trust Company. She began her literary career by writing poems, which were published by Victor B. Neuburg in the Sunday Referee. In 1936, she married an Australian journalist, Gordon Neil Stewart. After divorcing Stewart in 1949, Johnson married the novelist C. P. Snow (later Baron Snow) in 1950.

She wrote 27 novels. Her first novel, This Bed Thy Centre, was published in 1935. Her last novel, A Bonfire, was published in the year of her death, 1981. The fictional genres she used ranged from romantic comedy (Night and Silence Who is Here?) and high comedy (The Unspeakable Skipton) to tragedy (The Holiday Friend) and the psychological study of cruelty (An Error of Judgement). She also wrote two detective novels, jointly with her first husband Neil Stewart, under the joint pseudonym, Nap Lombard. She wrote seven short plays, six of them in collaboration with C. P. Snow. She had published a number of critical works, short stories, verse, sociological studies, and a collection of autobiographical essays. She reviewed extensively for magazines and newspapers and broadcast on the BBC radio program 'The Critics.'
