Jersey Shore is an American reality television series that ran on MTV from December 3, 2009, to December 20, 2012. The series follows the lives of eight housemates at a vacation home, for seasons one, three, five, and six on the Shore in Seaside Heights, New Jersey; plus for season two in South Beach, Florida; and for season four in Florence, Italy.

The show debuted amid controversy regarding its use of the terms guido and guidette and its portrayal of Italian Americans, which some alleged perpetuated stereotypes. It was also criticized by locals who observed that few of the cast members were natives or residents of the area. (Most of the cast was from New York, and at least two cast members were not of Italian descent.)

The show became a pop culture phenomenon with classes and conferences at universities about the show and journalists listing it as one of the most notable shows of the time. The Shore franchise spawned several international adaptations in other countries. Four of the Jersey Shore cast members received spin-off shows on MTV, with the most successful being Snooki & Jwoww. Most of the cast went on to appear in other reality programs or receive their own shows on various networks.

On August 20, 2017, a one-off television special called Reunion Road Trip: Return to the Jersey Shore aired on the E! network. On November 27, 2017, MTV announced that the cast (with the exception of Giancola) would be reuniting in Miami, Florida, for a new reunion series titled Jersey Shore: Family Vacation. The series premiered globally on April 5, 2018.

A spin-off series, All Star Shore, was released on June 29, 2022. It features Jersey Shore and other reality stars from around the world as they live together in a villa to compete for $150,000.
