International human rights law (IHRL) is the body of international law designed to promote human rights on social, regional, and domestic levels. As a form of international law, international human rights law are primarily made up of treaties, agreements between sovereign states intended to have binding legal effect between the parties that have agreed to them; and customary international law. Other international human rights instruments, while not legally binding, contribute to the implementation, understanding and development of international human rights law and have been recognized as a source of political obligation.

International human rights law, which governs the conduct of a state towards its people in peacetime is traditionally seen as distinct from international humanitarian law which governs the conduct of a state during armed conflict, although the two branches of law are complementary and in some ways overlap.

A more systemic perspective explains that international humanitarian law represents a function of international human rights law; it includes general norms that apply to everyone at all time as well as specialized norms which apply to certain situations such as armed conflict between both state and military occupation (i.e. IHL) or to certain groups of people including refugees (e.g. the 1951 Refugee Convention), children (the Convention on the Rights of the Child), and prisoners of war (the 1949 Third Geneva Convention).
