Jusepe Leonardo (1601–1652) was a Spanish painter of the Baroque period, active during his maturity in the court in Madrid.
He was born at Calatayud in Aragon, and was a pupil of Eugenio Caxés. He trained with Pedro de La Cueva, and became known for his battle paintings. He was painter to the king, and executed for the palace of Buen Retiro works worthy of celebrity; among them the Surrender of Breda and the March of the Duke of Feria‘s Troop upon Acqui. There is also a portrait of Alario the Goth in the Royal collections.
Leonardo was one of the artists used to decorate the Royal Alcázar restored by the King Felipe IV. Félix Castello and Leonardo painted the vaults of the Sacristy of the Chapel. He was unable to finish the Reliquary in the same chapel and in 1648, another painter was contracted. He apparently became an alcoholic, demented, and died at Zaragosa. His enemies were accused of having poisoned him.
