Newport Harbor: The Real Orange County (or simply Newport Harbor) is an MTV reality television series, documenting the lives of several teenagers of affluent families in Newport Harbor, a seaside community located in Orange County, California, United States. It differs from the usual reality show in that it is structured as a traditional narrative (seen more commonly in fictionalized television dramas or soap operas) than a straightforward observant documentary style.

The series premiered on August 13, 2007, and concluded on January 2, 2008. The series was created as a successor to Laguna Beach: The Real Orange County to avoid cancelling the series for lack of a fourth season plotline. However, Newport Harbor proved to be unsuccessful and was cancelled after two seasons.
