The 2010 Congressional election in the Northern Mariana Islands occurred on November 2, 2010 and elected the territory's Delegate to the United States House of Representatives. Representatives and non-voting Delegates are elected for two-year terms; the elected will serve in the 112th Congress from January 3, 2011 until January 3, 2013.
The race was considered to be highly competitive given Sablan's vulnerability, having been elected by less than a quarter of the vote in 2008, the strong Republican political environment, and the number of strong challengers.
