Advocacy evaluation has emerged in the past 20 years as a specialized area of evaluation practice. We offer a review of existing peer-reviewed literature and draw attention to the scarcity of scholarly work on human rights advocacy evaluation in the Global South. The lack of published material in this area is concerning, given the urgent need for human rights advocacy in the Global South and the difficulties of conducting advocacy in contexts in which fundamental human rights are often poorly protected. Based on the review of the literature and our professional experiences in human rights advocacy evaluation in the Global South, we identify themes in the literature that are especially salient in the Global South and warrant more attention. We also offer critical reflections on content areas not addressed in the existing literature and conclude with suggestions as to how activists, evaluators, and other stakeholders can contribute to the development of a field of practice that is responsive to the global challenge of advocacy evaluation.
