Dorothy Cisley Oldridge de la Hey (6 February 1884 – 18 November 1981) was an English educator who was one of the pioneers in women's education in India. She was the founder of Queen Mary's College in Madras, Madras Presidency in British India in 1914. It is the third oldest women's college in India.
