The immense popularity and wide recognition of J. K. Rowling's Harry Potter fantasy series has led to its being extensively parodied, in works spanning nearly every medium.
 The franchise holds the record for the most fan fiction parodies, at over 900.000 Some self-described parodies have been targeted by Rowling and her publishers as plagiarism, while others have sold hundreds of thousands of copies without any threat of legal sanction.
 Misinterpretations of "Harry Potter" parodies have sparked at least two urban legends.
 Many "Harry Potter" parodies are self-published; others are put out as part of major comic productions, such as "Mad", "The Simpsons", "South Park", "Saturday Night Live" and "Robot Chicken", all of which have parodied "Harry Potter" several times.
 Rowling has also been parodied (and parodied herself) in a number of instances.
