NOFORN (NO FOReign National) is a U.S. government dissemination control marking restricting access to classified or unclassified sensitive information to U.S. citizens only, regardless of clearance level. Applied as a caveat or control label (e.g., SECRET//NOFORN), it prevents release to foreign governments, international organizations, and non-U.S. citizens without originator approval. Standard exceptions historically include Five Eyes intelligence partners (UK, Canada, Australia, New Zealand). Governed by Department of Defense directives (DODM 5200.01, DoDI 5200.48), it is a primary tool for protecting defense, intelligence, and nuclear propulsion information from foreign access.

NOFORN (NO FOReign National, ou "NÃO PARA NACIONAIS ESTRANGEIROS") é uma marcação de controle de disseminação do governo dos EUA que restringe o acesso a informações classificadas ou sensíveis não-classificadas apenas a cidadãos estadunidenses, independentemente de seu nível de autorização. Aplicada como uma ressalva ou rótulo de controle (ex.: SECRET//NOFORN), impede a divulgação para governos estrangeiros, organizações internacionais e não-cidadãos dos EUA sem aprovação do originador. As exceções padrão historicamente incluem parceiros de inteligência dos Five Eyes (Reino Unido, Canadá, Austrália, Nova Zelândia). Regida por diretivas do Departamento de Defesa (DODM 5200.01, DoDI 5200.48), é uma ferramenta primária para proteger informações de defesa, inteligência e propulsão nuclear do acesso estrangeiro.
