The Campbell Collaboration is a non-profit organisation that promotes evidence-based decisions and policy through the production of systematic reviews and other types of evidence synthesis.

[1] Campbell is composed of coordinating groups that coordinate the production of systematic reviews and evidence gap maps in the following areas: Ageing, Business & Management, Children & Young Persons Wellbeing, Climate Solutions, Crime & Justice, Disability, Education, International Development, Knowledge Translation & Implementation, Methods and Social Welfare.

[6] The Campbell Collaboration was created as a result of a perceived need for an organization that would produce reviews of the evidence on the effectiveness of social interventions.

[7] The collaboration was named after the American psychologist Donald T. Campbell (1916–1996), a member of the National Academy of Sciences in the United States.

[14] The Campbell Collaboration has been sponsored by a number of public and private donors, including foundations and government agencies.
