Gaetano Ricciolini (27 August 1778, Florence – 9 October 1845, Rio de Janeiro) was an Italian bass-baritone and a choreographer who helped introduce opera and dance in South America. Ricciolini started his operatic career in Florence in the late 18th century. He moved to Portugal in 1805 as a soloist of the São Carlos National Theater, in Lisbon. There he met his wife, the Spanish-Portuguese soprano Isabel Rubio Ricciolini.
