An individual who is extremely infatuated with the Harry Potter series. Fans of the movies alone don't count. The difference between a mere fan and a Potthead is the difference between having read all of the books and having worn round glasses and a fake scar to not only the premiere of the movies, but the release date of the books.

Potthead (with two t's) is a term for someone who is obsessed with anything related to Harry Potter

NOT someone who is smokes pot. That would just be a pothead.
