Power sharing is a practice in conflict resolution where multiple groups distribute political, military, or economic power among themselves according to agreed rules. It can refer to any formal framework or informal pact that regulates the distribution of power between divided communities. Since the end of the Cold War, power-sharing systems have become increasingly commonplace in negotiating settlements for armed conflict. Two common theoretical approaches to power sharing are consociationalism and centripetalism.

At the state level, "power sharing is intended to hold the existing state together with the active participation and support of its minorities, unlike strategies of genocide, expulsion, partition and control".

Alternatives to power sharing may include coercive assimilation, assimilationist strategies, integrationist strategies, accommodationist strategies, multiculturalism, consociation

and territorial pluralism.

Broadly, power-sharing agreements contain provisions relating to at least one of the following: Political, economic, military, or territorial control.

Political power-sharing involves rules governing the distribution of political offices and the exercise of decision-making powers. Power may be shared by guaranteeing the inclusion of all significant parties simultaneously in the governing cabinet through rules on grand coalition formation. Alternatively, it may involve sharing power by guaranteeing sequential access to political office, like a rotating premiership. Electoral systems can provide power-sharing through political proportionality, which better allows for minority groups to remain competitive and win a portion of political power through democratic elections.

Proportionality also informs economic power-sharing, as the distribution of public resources may be instituted respective to the size of communities. In neopatrimonial systems, political office may also be closely related to economic opportunity, meaning an equitable distribution of political power overlaps with economic power-sharing. even equitable distribution of political power overlaps with economic power-sharing.

Power-sharing theories make empirical and normative claims about the utility or desirability of power-sharing systems for conflict management in divided societies. Two salient power-sharing theories, which stake competing claims, are consociationalism and centripetalism. Empirically, each theory prescribes different systems for power-sharing, such as consociationalism's proportional voting compared to centripetalism's alternative vote.
