The Caliph of Constantine, full title, Ali Ben-Hamet, Caliph de Constantine and Chief of the Haractas, Followed by his Escort, is an oil-on-canvas painting by the French artist Théodore Chassériau, executed in 1845.

This painting in the orientalist style is a good example of the "passion for color and movement" that gripped Chasseriau at this time.

The equestrian portrait represents Ali Ben Ahmed, the leader of the Haraktas, in Algeria, who had invited Chassériau during his visit to Paris.

The painting was exhibited at the Salon of 1845, where it received mixed reviews.

[2] Chassériau was accused of doing a "harmful imitation of the art of Delacroix", although the painting was described as "full of grandeur and majesty".
