Rafael Casanova i Comes (; 1660 – 2 May 1743) was a Catalan jurist and supporter of Charles VI, Holy Roman Emperor as a claimant to the Crown of Spain during the War of the Spanish succession. He became mayor of Barcelona and commander in chief of Catalonia during the Siege of Barcelona until he was wounded in combat while commanding La Coronela during the counterattack on the Saint Peter front on the last day of the siege, 11 September 1714. After the war he received a royal pardon for having supported the Habsburg claim to the Spanish throne. He recovered from his wounds, and continued his fight against absolute monarchy as a lawyer. It has been claimed that he is the author of the book "Record de l'Aliança fet el Sereníssim Jordi Augusto Rey de la Gran Bretanya" (Remembrance of the Alliance to George I of Great Britain) in which Catalonia reminds England of the Treaty of Genoa and their obligation to Catalonia.
