Juan de Valdés Leal (4 May 1622 – 15 October 1690) was a Spanish painter and etcher of the Baroque era.

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.

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 and his wife had five children, several of whom were also artists: Lucas, Juan, Maria, and Laura.
