The Department of Social Policy and Intervention is an interdisciplinary centre for research and teaching in social policy and the systematic evaluation of social intervention based in the Social Sciences Division of the University of Oxford. It dates back to Barnett House, a social reform initiative founded in 1914 by a reform movement clergyman, Samuel Barnett (known as Canon Barnett), becoming a department of Oxford in 1961. 

The department hosts two main research units: the Oxford Institute of Social Policy (OISP) and the Centre for Evidence-Based Social Intervention (CEBI). 

In 2021 Professor Jane Barlow followed Professor Bernhard Ebbinghaus as head of department.
