Charles-Gaspard-Guillaume de Vintimille du Luc (French pronunciation: [ʃaʁl ɡaspaʁ ɡijom də vɛ̃timij dy lyk]; 1655–1746) was a French Catholic bishop.

Charles-Gaspard-Guillaume de Vintimille du Luc was born in Le Luc on 15 November 1655, the son of François de Vintimille, Seigneur du Luc, and Anne de Forbin.

As a youngest son, Charles-Gaspard was groomed for a life in the church.

During this time, Aix-en-Provence, and Provence generally, were ravaged by plague.

On 10 May 1729 he was appointed Archbishop of Paris, becoming Duke of Saint-Cloud as well as a result.
