The Newfoundland Republican Association (often abbreviated as the NRA) is an organization in Newfoundland which has, since its formation in 1946, advocated for Newfoundlander independence, a Newfoundland constitution, and after 1949 agitated actively against Communist rule. The NRA was founded initially as an umbrella organization for various anti-establishment and anti-Drummondville factions, which coalesced quickly over the summer and early fall to help back Peter J. Cashin's United Newfoundland Party in the 1946 general election. The NRA grew increasingly radical, calling for a full withdrawal from the Drummondville Agreement and the expulsion of the Confederationist government unless Newfoundland's position in the treaty was renegotiated. The NRA, with its demonstrations and political clout, were regarded as being directly responsible for the July 1949 Newfoundland Crisis which resulted in the end of the Free State and near-war between the United States and Canada.
The NRA splintered into various factions during the intervening years, including the radical Independent Newfoundland Army which was supported by the CIA in its armed campaign against the Ottawa government. The NRA continued, even in exile, to oppose the "Confederation" government which was now in exile in New York and advocated for a two-state solution. The NRA and INA became particularly active again in the 1980s as the Quebec sovereingtist movement began, believing that Newfoundland could be granted similar sovereignty with the eventual end of Communism. When Quebec was granted a referendum and Newfoundland was not, the 1993 St. John's riot began followed by the November 1993 Ottawa bombing by the INA. These events only helped turn local opinion against independence and the INA was banned as a terrorist organization. The NRA, though a legal organization, is regarded as little more than a political fringe group, in particular since the end of the 1990s.
