Distributive justice concerns the socially just allocation of resources. Often contrasted with just process, which is concerned with the administration of law, distributive justice concentrates on outcomes. This subject has been given considerable attention in philosophy and the social sciences. Theorists have developed widely different conceptions of distributive justice. These have contributed to debates around the arrangement of social, political and economic institutions to promote the just distribution of benefits and burdens within a society. Most contemporary theories of distributive justice rest on the precondition of material scarcity. From that precondition arises the need for principles to resolve competing interest and claims concerning a just or at least morally preferable distribution of scarce resources.

In social psychology, distributive justice is defined as perceived fairness of how rewards and costs are shared by (distributed across) group members. For example, when some workers work more hours but receive the same pay, group members may feel that distributive justice has not occurred. To determine whether distributive justice has taken place, individuals often turn to the behavioral expectations of their group. If rewards and costs are allocated according to the designated distributive norms of the group, distributive justice has occurred.
