Portrait of Ambroise Vollard in a Red Headscarf (French:Ambroise Vollard au foulard rouge) is an 1899 oil on canvas portrait by Pierre-Auguste Renoir of his art dealer Ambroise Vollard.

The painting represents Renoir's late work period (1892–1919).

A large bald man, Vollard is pictured in this portrait in profile dressed in a brown wool cloth suit, with characteristically downcast eyes.

He wears a red headscarf that has been tied behind his neck, which serves as a reminder of his origins and upbringing on the Indian Ocean island of Réunion.

[1] Vollard was not averse to posing for a portrait and was painted by Renoir on at least two other occasions (conventionally suited in 1908 and dressed as a matador in 1917), as well as by some of Renoir's contemporaries.
