The Portrait of a Gonfaloniere is a painting by the Italian baroque artist Artemisia Gentileschi.

[2] An armor-clad man is shown in full-length view, with his left hand on the hilt of his sword and his right resting on a table covered in red velvet.

He is further adorned with an elaborate white ruff and cuffs, as well as a green sash draped over his left shoulder.

The insignia on his breastplate may indicate membership in the Order of Saints Maurice and Lazarus, an organization sworn to defend the papacy, even in battle.

[3] The painting is first recorded as being in the collection of Agostino Pepoli, a member of an aristocratic family in Bologna.
