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

The show debuted amid controversy regarding its use of the terms "Guido/Guidette", its portrayal of Italian-Americans and allegations of perpetuating stereotypes, as well as criticism from locals that the cast members were not residents of the area. (Most were from New York, and at least two of them were not Italian).

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 would go 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.
