A Very Potter Senior Year (often shortened to AVPSY) is a musical written by Matt Lang, Nick Lang, and Brian Holden with songs by Clark Baxtresser, Pierce Siebers, A. J. Holmes, and additional songs by Darren Criss. It is the conclusion of the Very Potter trilogy of Harry Potter-inspired musicals produced over four years by StarKid Productions. Rather than a full musical, as with its previous installments, the production took the form of a live staged reading of the script with performances of the songs at LeakyCon in Chicago, Illinois, on August 11, 2012. It featured nearly all of the StarKid actors and actresses who had starred in previous StarKid shows to date, including actor Darren Criss, who returned to the company to reprise his role as Harry Potter, and Evanna Lynch as Luna Lovegoo
