List of political parties in the Northern Mariana Islands

This article lists political parties in the Northern Mariana Islands. The Northern Marianas has a multi-party system, with two or three strong parties and a third party that is electorally successful. As of 28 April, 2024, The Democratic Party and the Republican Party are the only two parties represented in elected and appointed offices, though the independents are a majority in the house and make up one-third of the senate.

The Covenant Party was a political party advocating governmental and financial reform. It was named after the Covenant to Establish a Commonwealth of the Northern Mariana Islands in Political Union with the United States of America, Act of Mar. 24, 1976, Pub. L. 94-241, 90 Stat. 263, codified as amended at 48 U.S.C. § 1801 note. The Covenant Party is considered de facto dissolved when Governor Eloy Inos departed the party and rejoined the GOP in 2013. Many left the party soon after, most moving to the Republic Party, making it a de facto GOP absorption of the Covenant Party.

The Reform Party was a political party that was not an affiliate of the Reform Party USA but rather the American Reform Party, a splinter group of that party. The party was founded in 1999 by former Governor Froilan C. Tenorio, who claimed to be disgruntled and tired of the disunity showed by his former political affiliation, the Democrats. In 2002, the party merged back into the Democratic Party.
