Francisco Villela Barbosa (1769–1846) was a Portuguese mathematician. He graduated from the University of Coimbra in 1796, earning a degree in mathematics. His early career was spent as a professor of geometry at the Royal Navy Academy in Lisbon. Barbosa later became a noted poet and Brazilian civil servant. Author of several geometry texts, he intended his 1817 Breve Tratado de Geometria Spherica as a supplement to one of those books.
