The '''North Warning System''' (NWS, {{langx|fr|Système d'alerte du nord}}) is a joint United States and Canadian [[early-warning radar]] system for the atmospheric [[air defense]] of North America. It provides surveillance of airspace from potential incursions or attacks from across North America's polar region. It replaced the [[Distant Early Warning Line]] system in the late 1980s.
