Belly, the main character from "The Summer I Turned Pretty," lives in Philadelphia, Pennsylvania. This has been subtly confirmed in the series by the Pennsylvania license plates seen on her mother's car and references to growing up in the suburbs of Philadelphia. Although Belly spends her summers at the fictional Cousins Beach in Massachusetts at the beach house owned by her mother's best friend, Susannah, her actual home is in Philadelphia. The Fisher brothers from the series live in Boston, Massachusetts, while Cousins Beach is depicted as a summer getaway rather than Belly's permanent residence.
