May Hollinworth (1 May 1895 – 19 November 1968) was an Australian theatre producer and director, former radio actress, and founder of the Metropolitan Theatre in Sydney. The daughter of a theatrical producer, she was introduced to the theatre at a young age. She graduated with a science degree, and worked in the chemistry department of the University of Sydney, before being appointed as director of the Sydney University Dramatic Society. She held that post from 1929 to 1943, when she resigned and founded the Metropolitan Theatre, which she directed from 1944 to 1950. She presented a range of dramatic works, including Shakespeare and other classics, and contemporary plays from Australia and around the world. She premiered several Australian plays. She retired from the Metropolitan Theatre in 1950 due to illness, but was later invited to direct plays at the Independent Theatre and the Elizabethan Theatre in Sydney. She had a reputation as a superb producer, known for her highly effective use of lighting, and her abilities to arrange actors on stage to convey dramatic meaning visually, to overcome the challenges of large and small stages with minimal facilities, and to select and nurture a cast. Many actors who became notable in Australia and other countries played under her direction at the start of their careers.
