Avis Mary Dry (30 April 1922 – 26 January 2007) was a clinical psychologist and an author on the psychology of Carl Jung.
Although British by birth, she spent much of her early life in New Zealand after her parents emigrated when she was five.
She returned to England in 1956, where she obtained her PhD in Psychology from the University of Leeds.
Dry worked briefly as a psychologist at Denby Hospital in Wales, before she took a research psychology post at the C. G. Jung Institute in Zürich, Switzerland.
Based on her doctoral studies, Dry tried to provide a neutral assessment of Carl Jung's work, in response to other books that had taken both very pro-Jung and very anti-Jung stances.
