Jean Aylwin (10 October 1885 – 1964), also known as Jean Isabella Griffin Aitkin, was a Scottish actress and singer, often billed as "The Lady Harry Lauder". Aylwin was best known for creating character roles in successful Edwardian musical comedies early in the 20th century. She turned to roles in non-musical plays by World War I, continued to act into the 1920s and was later a radio broadcaster. Her divorce in 1924 from a colonel in the Intelligence Corps involved allegations of infidelity.
