Ravenclaw's common room is located in Ravenclaw Tower on the west side of Hogwarts.

You might belong in Gryffindor,
Where dwell the brave at heart,
Their daring, nerve, and chivalry
Set Gryffindors apart.
You might belong in Hufflepuff,
Where they are just and loyal,
Those patient Hufflepuffs are true
And unafraid of toil.
Or yet in wise old Ravenclaw
If you've a ready mind
Where those of wit and learning
Will always find their kind.
Or perhaps in Slytherin
You'll make your real friends
Those cunning folk use any means
To achieve their ends.
