Xavier María de Munibe and Idiáquez , better known as Conde de Peñaflorida (1723-1785) was an Illustrated Spanish writer. Xavier María de Munibe e Idiáquez, Conde de Peñaflorida (Count of Peñaflorida) (Azkoitia, 1723—Bergara, 1785), was an important figure of Enlightenment Spain. He founded the Royal Basque Society of Friends of the Country in Bergara in 1748, which would become the first Sociedad Económica de los Amigos del País, a society inextricably linked to the Real Compañía Guipuzcoana de Caracas.
Peñaflorida was the author of many works in his lifetime. They include Los aldeanos críticos (1758),Ensayo de la Sociedad Bascongada de amigos del país (1766), and Gabon-Sariac (1762) a religious epic dealing with the life of Louise de La Vallière (although some attribute this one to Manuel Larramendi). He also wrote the music and librettos of two bilingual (Spanish-Basque) comic operas, El borracho burlado(1764) and Comedia famosa.
