Ravenclaw House is one of four houses at the Hogwarts School of Witchcraft and Wizardry. As with the other Hogwarts houses, Ravenclaw has unique features setting it apart from the other houses. Ravenclaw students are "sorted" here only if they meet the expectations of the Ravenclaw founder. Ravenclaw students must be highly intelligent and possess a love of learning

It is strange to think that the Sorting Hat did not put Hermione Granger into the House of Ravenclaw, since Hermione is undoubtedly one of the brightest students at the school. Perhaps the Hat realized that her other characteristics, such as bravery, loyalty, and unalterable commitment to being a good person, would stand her in good stead in the House of Gryffindor. It is probably a good thing she did end up with Ron and Harry in Gryffindor, because these three have an important role to play in defeating the Dark Lord, and it is good they found each other early in their school career.

Founded by Rowena Ravenclaw (a lady coming from Glen, known for her creativity as well as her superior intelligence), this is the house that encourages those students who are wise and sharp, and have great wits and capability for learning. In other words, this is the house for the brainy. Its bronze- and blue-colored blazon depicts a golden colored eagle, against a field of blue.

This house, located in the "Ravenclaw Tower", has its common room situated in the west section of the Hogwarts castle. In all major events between houses, such as Quidditch matches, Ravenclaw players dress in blue. The house ghost is The Grey Lady, a woman with outstanding intellect, who could not find herself a true love.

The head of the House of Ravenclaw is Professor Filius Flitwick, known for his short height and squeaky voice. This Charms teacher is one of those teachers respected by students, in spite of his nature that is at times known to be quite sensitive. This is mostly because of the calm placid manner in which he deals with his students. Among the most prominent figures from this house during Harry Potter's tenure at Hogwarts are Filius Flitwick, Luna Lovegood, Penelope Clearwater, Padma Patil, Roger Davis, Terry Boot, Lisa Turpin, and Anthony Goldstein. Among these students of the House of Ravenclaw, one of the major attractions is Cho Chang, who continues to remain Harry's love interest for several of his years at Hogwarts. Another notable character is Luna Lovegood. While sometimes considered strange because of her perpetually dreamy looks and unconventional opinions, Harry finds her comfortable to be around, and she becomes part of his close circle of friends.
