Petunia Dursley is a fictional character from the Harry Potter Universe.
Petunia Dursley is wife of Vernon Dursley and mother of Dudley Dursley. She is known to spoil Dudley and call him babyish nicknames. She is the older sister of Lily Potter and was viewed as the worthless, less important sister. She was very jealous of her younger sister who was adored by their parents. Petunia was upset both when Lily received a letter from Hogwarts and nephew Harry did as well. She disliked whenever the Potters were mentioned as she liked to pretend they were not related. She therefore mistreated Harry when he lived with the Dursleys.
 Physical Appearance
Petunia Dursley, as described in the books, is thin and blonde and had twice the usual amount of neck, which she used to crane over garden fences to spy on their neighbors. In the movies, however, Petunia has brown hair.
