Eugenio Caxés (1577–1642) was a Spanish painter of the Baroque period.
He was born into a Florentine family in Madrid, and wrote his name in a variety of ways (Cajés, Cazés, Caxesi, and Caxete). His father, Patricio, was a disciple of Alessandro Allori and was recruited to Spain by the ambassador Luis de Requesens. Caxés painted in the royal palaces of King Philip II of Spain. He married the daughter of the disgraced Juan Manzano, master carpenter for the Escorial, who died in a fall from a scaffold.
Caxés was commissioned by the administration of King Philip III to decorate the room for royal audiences in Madrid, where he painted a Judgement of Solomon in the vault. He was appointed Painter to the King in August 1612. Most of his works were completed in Madrid. Along with Vincenzo Carducci he painted the chapel of Our Lady del Sagrario in Toledo, and the canvases of the Retablo Mayor del Monasterio de Guadalupe. He was awarded 11,000 reales for a large historical canvas on the History of Agamemnon (now lost). Among his pupils are Luis Fernandez and the barrister Valpuesta.
He was the editor of a biography of Spanish painters, called the Abecedario Pittorico. He opposed a fee proposed to extend the alcabala to painters.
