Cousins Beach is a fictional seaside town from the book and TV series The Summer I Turned Pretty , not a real‑world address you can punch into a map.

Where “Cousins” is supposed to be

  • In the story, Cousins Beach is described as a summer‑house community on the East Coast , with details pointing to a Cape Cod–style setting in Massachusetts (south of Boston).
  • Some fans and commentators place it roughly in the Cape Cod / South Shore region of Massachusetts , even though the author confirms it is invented.

Where it was filmed in real life

  • The TV version of Cousins Beach was filmed in Wilmington and the surrounding beaches in North Carolina , including Wrightsville Beach and nearby coastal spots.
  • So while “Cousins” doesn’t exist as a named town, you can visit the real‑life filming locations in coastal North Carolina to see the look and feel of the show.

If you tell me whether you mean the story setting or the filming locations , I can give you a more tailored breakdown (with a simple HTML table comparing book vs show “whereabouts”).
