Mark Ravizza is an American analytic philosopher best known for his collaboration with John Martin Fischer on moral responsibility and free will. Together they developed a sophisticated compatibilist account grounded in 'reasons-responsiveness,' arguing that an agent is morally responsible when their action flows from a mechanism that is appropriately sensitive to reasons. His work has been influential in connecting metaphysical questions about agency with normative questions about accountability.
