Gustav Jahoda (11 October 1920 – 12 December 2016) was an Austrian psychologist and writer.

He was educated in Vienna, then subsequently in Paris and London. He studied sociology and psychology at London University before obtaining a lectureship in social psychology at the University of Manchester. In 1952 he took up a post at the University College of the Gold Coast (now Ghana) in the Department of Sociology, where he carried out pioneering research into cross-cultural psychology.

In 1963, Gustav Jahoda was invited to set up a new psychology department in the University of Strathclyde, although he continued to make field trips to West Africa. He retired in 1985.

He published works on cross-cultural psychology, socio-cognitive development and history of the social sciences. He also published more than 200 articles. Jahoda was elected fellow of the British Academy in 1988 and fellow of the Royal Society of Edinburgh in 1993.
