Cambridge SCA (Cambridge Student Community Action) is a registered charity which facilitates community volunteering opportunities for the students of the University of Cambridge in England. Projects typically serve the local community. Cambridge SCA runs 10 of its own 'Internal Projects', each led by student Project Leaders. These include educational projects and projects to help children and elderly people. Additionally, they offer volunteering opportunities through external organizations, such as Cambridge Carbon Footprint, Headway, and the Cambridge Rape Crisis Centre.

Cambridge SCA became a registered charity in 1972. It is one of the longest-running student charity organizations affiliated with the University of Cambridge.

Cambridge SCA is managed by a student committee, a board of trustees (including three members from the student committee), and a body of representatives. Project Leaders oversee their respective projects with support from the student committee. Two staff members handle the daily operations of the charity and serve as the first point of contact for volunteers, committee members, and community members seeking assistance from SCA projects.

Elections for the student committee occur at the Annual General Meeting, held at the end of Cambridge's Lent term.
