Rafael Tegeo Díaz (27 November 1798, Caravaca de la Cruz - 3 October 1856, Madrid) was a Spanish Neoclassical painter, known primarily for his portraits.
After displaying an early affinity for drawing, he was enrolled at the "Real Sociedad de Amigos del País" in Murcia, where an Italian sculptor named Santiago Baglietto introduced him to Greek sculpture.
His canvases of Francis, Duke of Cádiz and Queen Isabel II won him an appointment as court painter.
He is also known for a series of posthumous portraits of famous Admirals and other officials related to the Spanish Navy, now at the Museo Naval de Madrid.
In 2015, the Ayuntamiento of Caravaca announced the forthcoming publication of a new book, Rafael Tegeo: Del tema clásico al retrato romántico, by Martín Páez Burruezo (b.1948).
