行动研究（Action research）是一种参与干预性的社会研究方法，研究者参与到行动中以规划、实施、监测行动的变化，并利用研究者的理论与经验服务于被研究对象。

Action research is either research initiated to solve an immediate problem or a reflective process of progressive problem solving led by individuals working with others in teams or as part of a "community of practice" to improve the way they address issues and solve problems. There are two types of action research: participatory action research and practical action research. Denscombe (2010, p. 6) writes that an action research strategy's purpose is to solve a particular problem and to produce guidelines for best practice.
