J.K. Rowling's fictional village where Harry spends part of his childhood is Little Whinging.
Little Whinging is a fictional Surrey village and the home of Harry Potter's aunt and uncle, Petunia and Vernon Dursley, and their son Dudley. Harry lives at 4 Privet Drive, a suburban house where he is treated as an unwanted member of the household before learning that he is a wizard.
The first Harry Potter novel opens at Privet Drive, establishing the ordinary-looking setting that contrasts with the magical world Harry later discovers. The house also provides protection through his mother's blood connection: as long as Harry can call the Dursleys' home his home, a protective charm remains effective.
Little Whinging is not the same place as Godric's Hollow, where Harry was born, or Hogsmeade, the wizarding village near Hogwarts. The name is a play on “whinge,” a British term meaning to complain or grumble, fitting the Dursleys' disapproving attitude toward Harry's unusual life.
