Juan de Valdés Leal was a Spanish painter and etcher of the Baroque era.

Valdés was born in Seville in 1622. He became a painter, sculptor, and architect. By his twenties, he was studying under Antonio del Castillo in Córdoba.

Among his works are History of the Prophet Elias for the church of the Carmelites; Martyrdom of St. Andrew for the church of San Francesco in Córdoba; and Triumph of the Cross for la Caridad in Seville. He became friends with Bartolomé Esteban Murillo, who had a very different style; Leal tended to paint somber and dramatic subjects, while Murillo's style was peaceful and serene. After Leal returned to Seville in 1656, he and Murillo founded the Seville Academy of Art.

Several of his paintings treat the subjects of vanitas, transience and mortality. Two examples are In ictu oculi ("in the blink of an eye") and Finis gloriae mundi ("end of the world's glory"), painted for the Charity Hospital in Seville.

He married Isabella Carasquilla, daughter of Antonio Palomino, in 1647. She was also a painter. He and his wife had five children, several of whom were also artists: Lucas, Juan, Maria, and Laura. His daughters specialized in portrait miniatures. Valdés died in Seville in 1690. His wife died in Seville as late as 1730. Maria died a nun in the Cistercian Convent in Seville in 1730.
