Parvati Patil is a Gryffindor student in Harry's year and the twin sister of Ravenclaw student Padma Patil. Her best friend is Lavender Brown; they are particularly fond of Trelawney's Divination class, and share many common interests. In Philosopher's Stone, she sticks up for the helpless Neville after Malfoy mocks him and steals his Remembrall during the first-year students' flying class, and is then teased by Pansy Parkinson, who laughed at Parvati's supposed love for "fat little cry babies". Parvati attends the Yule Ball with Harry in Goblet of Fire, but her evening is a disappointment as Harry spends the evening jealously preoccupied with Cho Chang's date with Cedric Diggory and disdains dancing with Parvati; she eventually abandons him to dance with a Beauxbatons boy whom she then later meets in Hogsmeade.
In her fifth year, Parvati joins Dumbledore's Army along with her sister. In Half-Blood Prince, the twins are almost removed from Hogwarts by their parents, and ultimately do return home after Dumbledore's death. However, the Patil twins return to their seventh year at Hogwarts, and they are first seen in the final book before the Battle of Hogwarts. Parvati duels with the Death Eater Travers during the battle, and attacks Antonin Dolohov with a Body-Bind Curse after he attempts to retaliate at Dean for stunning another Death Eater.
The Patils' names and appearance in the films imply that they are of Indian descent. Patil is a common Maratha surname in the state of Maharashta, India. Rowling originally intended the twins' first names to begin with "Ma", and on her classlist from Harry Potter and Me, their last name was spelled as Patel. Parvati is also the name of one of the three primary Hindu goddesses.
Parvati was portrayed by Sitara Shah in Prisoner of Azkaban. Sefali Chowdhury took over the part for Goblet of Fire, along with the film and game versions of Order of the Phoenix and Half-Blood Prince.
