Parsifal is a music drama in three acts by the German composer Richard Wagner and his last composition. Wagner's own libretto for the work is freely based on the 13th-century Middle High German chivalric romance Parzival of the Minnesänger Wolfram von Eschenbach and the Old French chivalric romance Perceval ou le Conte du Graal by the 12th-century trouvère Chrétien de Troyes, recounting different accounts of the story of the Arthurian knight Parzival (Percival) and his spiritual quest for the Holy Grail.

Wilhelm Richard Wagner was a German composer, theatre director, polemicist, and conductor who is chiefly known for his operas. Unlike most opera composers, Wagner wrote both the libretto and the music for each of his stage works. Initially establishing his reputation as a composer of works in the romantic vein of Carl Maria von Weber and Giacomo Meyerbeer, Wagner revolutionised opera through his concept of the Gesamtkunstwerk, by which he sought to synthesise the poetic, visual, musical and dramatic arts, with music subsidiary to drama. He described this vision in a series of essays published between 1849 and 1852. Wagner realised these ideas most fully in the first half of the four-opera cycle Der Ring des Nibelungen.
