The Jester Named Don John of Austria is a portrait by Velázquez, now in the Museo del Prado in Madrid.

The subject's real name is unknown, but he came to be nicknamed after John of Austria, the son of Charles V, well known for his victory at Lepanto.

He is shown dressed in a general's cloak and black doublet, is surrounded by abandoned helmets, armour and weapons, and with a fragment of a battle-scene of Lepanto in the background.

Around 1635-40 this lodge was one of Philip IV's main architectural projects, since he was a great hunting fanatic who wanted somewhere to rest during the long time he spent on that pastime.

Its other homes have been the Palacio del Buen Retiro (1701–1716), the Royal Palace of Madrid (1772–1816) and the Real Academia de Bellas Artes de San Fernando (1816–1827), before it finally moved to its current home at the Prado in 1827.
