Joseph of Cupertino (Copertino), OFM Conv. (Italian: Giuseppe da Copertino; 17 June 1603 – 18 September 1663) was an Italian Conventual Franciscan friar who is honored as a Christian mystic and saint. According to traditional Franciscan accounts, he was "remarkably unclever", but experienced miraculous levitation and ecstatic visions throughout his life which made him the object of scorn. He applied to the Conventual Franciscan friars, but was rejected due to his lack of education. He then pleaded with them to serve in their stables. After several years of working there, he had impressed the friars so much with the devotion and simplicity of his life that he was admitted to their Order, destined to become a Catholic priest, in 1625.

The Order of Friars Minor Conventual (O.F.M.Conv.) is a male religious fraternity in the Catholic Church and a branch of the Franciscan Order. Conventual Franciscan Friars are identified by the affix O.F.M.Conv. after their names. They are also known as Conventual Franciscans or Minorites.
