Renaud (or Renaut or Renault) de Montauban (Modern French: [ʁəno d(ə) mɔ̃tobɑ̃]; German: Reinhold von Montalban; Italian: Rinaldo di Montalbano; Dutch: Reinout van Montalban or Montalbaen) was a legendary hero and knight which appeared in a 12th-century Old French chanson de geste known as The Four Sons of Aymon. The four sons of Duke Aymon are Renaud, Richard, Alard and Guiscard, and their cousin is the magician Maugris (French: Maugis; Italian: Malagi or Malagigi). Renaud possesses the magical horse Bayard and the sword Froberge (French: Flamberge; Italian: Fusberta or Frusberta).

The story of Renaud was popular across Europe. The tale was adapted into Dutch, German, Italian and English versions throughout the Middle Ages, inspired the Old Icelandic Mágus saga jarls, and also incited subsequent sequels and related texts that form part of the Doon de Mayence cycle of chansons. Renaud, as Rinaldo, is an important character in Italian Renaissance epics, including Morgante by Luigi Pulci, Orlando Innamorato by Matteo Maria Boiardo and Orlando Furioso by Ludovico Ariosto.
