Oppression is the exercise of authority or power in a burdensome, cruel, or unjust manner. It can also be defined as an act or instance of oppressing, the state of being oppressed, and the feeling of being heavily burdened, mentally or physically, by troubles, adverse conditions, and anxiety.

The systematic; socially supported mistreatment and exploitation of a group or category of people by anyone.

"Institutional Oppression occurs when established laws, customs, and practices systematically reflect and produce inequities based on one’s membership in targeted social identity groups. If oppressive consequences accrue to institutional laws, customs, or practices, the institution is oppressive whether or not the individuals maintaining those practices have oppressive intentions."

Anarchists and other libertarian socialists argue that police and law themselves are oppression. The term oppression in such instances to refer to the subordination of a given group or social category by unjust use of force, authority, or societal norms in order to achieve the effects noted above. When institutionalized, formally or informally, it may achieve the dimension of systematic oppression. Oppression is customarily experienced as a consequence of, and expressed in, the form of a prevailing, if unconscious, assumption that the given target is in some way inferior. Oppression is rarely limited solely to formal government action: an individual may be the particular focus of oppression or persecution and in such circumstances have no group membership in which to share, and thus maybe mitigate, the burden of ostracism.
