International law is the set of rules, norms, and standards generally recognized as binding between states. It establishes norms for states across a broad range of domains, including war and diplomacy, economic relations, and human rights. International law differs from state-based domestic legal systems in that it is primarily, though not exclusively, applicable to states, rather than to individuals, and operates largely through consent, since there is no universally accepted authority to enforce it upon sovereign states. States may choose to not abide by international law, and even to breach a treaty but such violations, particularly of peremptory norms, can be met with disapproval by others and in some cases coercive action ranging from diplomatic and economic sanctions to war.

अन्तरराष्ट्रीय विधि से आशय उन नियमों से है। जो स्वतन्त्र देशों के बीच परस्पर सम्बन्धों (विवादों) के निपटारे के लिये लागू होते हैं। अन्तरराष्ट्रीय विधि किसी देश के अपने कानून से इस अर्थ में भिन्न है कि अन्तरराष्ट्रीय विधि दो देशों के सम्बन्धों के लिए लागू होता है न कि दो या अधिक नागरिकों के बीच।
