Stephen Jan Ticktin (born 1946) is a retired Canadian psychiatrist, therapist and lecturer, and a notable figure in the anti-psychiatry movement.
After earning his medical degree from the University of Toronto in 1973, Ticktin became personal assistant to anti-psychiatry movement leader David Cooper, travelling with him through Europe, North America, South America and Mexico on his lecture tours (1972–1976). He also studied with the Philadelphia Association and apprenticed in existential therapy with R.D. Laing. In 1983, Ticktin obtained an MRCPsych in Psychiatry through the Royal College of Psychiatrists in London, and in the course of the decades during which Ticktin made the UK his home, he helped to found the British Network of Alternatives to Psychiatry and the Supportive Psychotherapy Association.
He joined the editorial collective of Asylum in 1987 and has published articles in a number of British psychiatry journals. Ticktin has also been a visiting lecturer and supervisor at the Regent's College School of Psychotherapy and Counselling, and at The New School of Psychotherapy and Counselling at Schiller International University, where he worked with Emmy van Deurzen. In 2004, he returned to Canada where he saw patients in private practice and was also adjunct faculty at the Living Institute in Toronto.
