Parzival is a medieval romance by the knight-poet Wolfram von Eschenbach in Middle High German. The poem, commonly dated to the first quarter of the 13th century, centers on the Arthurian hero Parzival (Percival in English) and his long quest for the Holy Grail following his initial failure to achieve it.

Parzival begins with the knightly adventures of Parzival's father, Gahmuret, his marriage to Herzeloyde (Middle High German: herzeleide, "heart's sorrow"), and the birth of Parzival. The story continues as Parzival meets three elegant knights, decides to seek King Arthur, and continues a spiritual and physical search for the Grail. A long section is devoted to Parzival's friend Gawan and his adventures defending himself from a false murder charge and winning the hand of the maiden Orgeluse. Among the most striking elements of the work are its emphasis on the importance of humility, compassion, sympathy and the quest for spirituality. A major theme in Parzival is love: heroic acts of chivalry are inspired by true love, which is ultimately fulfilled in marriage.

Regarded as one of the masterpieces of the Middle Ages, the romance was the most popular vernacular verse narrative in medieval Germany, and continues to be read and translated into modern languages around the world. Wolfram began a prequel, Titurel, which was later continued by another writer, while two full romances were written adapting Wolfram's story of Loherangrin. Richard Wagner based his famous opera Parsifal, finished in 1882, on Parzival.
