Ronald “Ron” Bilius Weasley (born 1 March 1980) is a fictional character in J. K. Rowling’s Harry Potter series. He has been portrayed by actor Rupert Grint in all Harry Potter films so far.

Ron’s two best friends at Hogwarts School of Witchcraft and Wizardry are Harry Potter, the main character of the series, and Hermione Granger.

Ron was born to Arthur and Molly Weasley, members of a well-known pure-blood Wizarding family. Ron is the sixth of seven children, and is the youngest son. Ron grew up in The Burrow, near the village of Ottery St. Catchpole in Devon. Most of his friendly Gryffindor classmates call him “Ron”, with the exception of Luna Lovegood, who calls him by his full name, and Lavender Brown, who briefly used the endearment “Won-Won” while they were dating. Draco Malfoy and other less-than-friendly students from rival Hogwarts Houses generally call him “Weasley”.

At the beginning of the series, Arthur Weasley is head of the Misuse of Muggle Artifacts Office, a minor division the Ministry of Magic’s Department of Magical Law Enforcement. This is an impressive sounding position, but one which barely earns Mr. Weasley enough to support his large family. Throughout the series, Ron is very self-conscious of his family’s poverty.

Ron has five older brothers, Bill, Charlie, Percy, twins Fred and George, and a little sister Ginny. His older brothers have each excelled in various ways; Ron often feels lost in the shadow of their accomplishments and has a great desire to be noticed in his own right. It can be seen that Ron’s craving for attention causes him to have arguments with Harry and Hermione, when he feels that he is sidestepped by others in front of his best friends. Ron is initially overshadowed by them both, with Harry and Hermione both being more famous at Hogwarts than him, and resents it, but ultimately, his loyalty towards his friends is unquestionable. As he grows older Ron begins to reveal his own abilities and is made a prefect. Ron seems to have a growing romantic interest in Hermione Granger which was hinted at from the fourth book.

Ron is an excellent chess player and usually beats his best friends at Wizard Chess.

Ron has a typical sardonic sense of humour and his biting comments, though usually very funny, tend to offend or insult others. At times Ron appears to be the most emotional and impulsive of the three central characters, often going with what his feelings dictate any given moment as opposed to thinking things through, which has unfortunately cast him as something of an oaf in the eyes of some. When given an opportunity, Ron takes full advantage to be in the spotlight.
