Political rehabilitation is the process by which a disgraced member of a political party or a government is restored to public respectability and thus political acceptability. The term is usually applied to leaders or other prominent individuals who regain their prominence after a period in which they have no influence or standing, including deceased people who are vindicated posthumously. Historically, the concept is usually associated with Communist states and parties where, as a result of shifting political lines often as part of a power struggle, leading members of the Communist Party find themselves on the losing side of a political conflict and out of favour, often to the point of being denounced, imprisoned or even executed.

Rehabilitation committees () considered appeals from both the Central Committee of the Chinese Communist Party as well as from petitions—often in the form of big-character posters—by ordinary citizens. Reformer Hu Yaobang led a series of rehabilitations from 1978 to 1981 of people persecuted by the Gang of Four during the Cultural Revolution (1966–1976).
