Margaret Johnston (10 August 1914, Sydney, Australia – 19 June 2002, Kingston upon Thames, England) was an Australian-born British actress. Johnston was most widely admired for her stage performances, but also appeared in 12 films and a handful of TV productions before retiring from acting in 1968 to devote herself to running a theatrical agency. Johnston was the second of three daughters born in Australia to English parents. She was educated at the prestigious North Sydney Girls High School, then at the University of Sydney where she studied Law. Johnston had shown an interest in, and aptitude for, drama from an early age and had acted in various school productions before later graduating to professional productions in Sydney's theatres. It was reported that her oft-stated ambition at this time was "to move to Europe, to learn her craft, and to lose her (Australian) accent". In 1936, Johnston (accompanied by her sisters) travelled to England in order to pursue her career. She was accepted as a student by the Royal Academy of Dramatic Art, where she was tutored by Stefan Hock.
