The Portuguese-Spanish Treaty of Friendship and Non-Aggression (, ), more commonly known as the Iberian Pact (Portuguese, Spanish: Pacto Ibérico), was an international treaty signed on 17 March 1939 between Portugal's right-wing dictatorship of the Estado Novo, under António de Oliveira Salazar, and Spain's nationalist right-wing dictatorship of Francisco Franco, who had just won the Spanish Civil War (1936–1939), in which he enjoyed Portuguese non-official collaboration. An additional protocol to the pact was signed on 29 July 1940.
