Henri-Auguste de Loménie, (1594 – 3 November 1666), Count of Brienne, Seigneur de La Ville-aux-Clercs was a French politician. He was secretary of state for the navy from 1615 to February 1643, and then secretary of state for foreign affairs from 1643 to 1663 under Mazarin during the minority of Louis XIV. From the Loménie family (originating in Flavignac in Limousin), he was the son of Antoine de Loménie, secretary of state to Henry IV and a Huguenot convert.

The Comte de Brienne was naturally destined to public office. He traveled to Germany, Poland and Italy, by order of his father, the last as well prepare for his career. He was back in Paris towards the end of 1609, that he was noticed by Henry IV, who allowed him to attend the board sometimes. Marie de Medici, regent of France, commissioned him in 1614 to negotiate with some members of the États généraux, "whose minds were unwell", and his clever response obtained from them the nomination of a president acceptable to the court. This success earned him in 1617, master of ceremonies and provost of King's orders.

Hugues de Lyonne was charged in 1663, with the Department of Foreign Affairs, replacing him.

He died in 1666. Le Tellier, who became chancellor, said in council, when he heard the news: "He had never seen a man more intelligent in business, less shaken at the least danger, less stunned by surprises, and more fertile in expedients to disentangle them happily." And the King Louis XIV said:"I lost today the oldest, most loyal and most informed of my ministers."

He wrote his memoirs for the instruction of her children: Memory containing the most remarkable events of the reign of Louis XIII and Louis XIV than to the death of Cardinal Mazarin.
