Harry Potters scar is on his forehead, but the exact location is not specified in the books. In the movies, the scar is initially shown on the right side of his forehead in the first movie, but then switches to the left side in the third movie. However, the movies are not consistent in the placement of the scar. According to J.K. Rowling, the scar is on the right side of Harrys forehead. In the books, there are references to the scar being above Harrys right eye. Therefore, the location of Harry Potters scar is not definitive, but it is generally accepted that it is on the right side of his forehead.
