Jean de Dinteville (1504–1555) was a French nobleman and a diplomat, who has been serving as a French ambassador to England.
He is the left-hand figure in Holbein's 1533 painting The Ambassadors, painted whilst he was French ambassador to London, and which he presumably commissioned. He was younger brother of François de Dinteville, Bishop of Auxerre. Dinteville's motto was Memento mori, meaning "Remember thou shalt die."[1]
