Aymar-Joseph de Roquefeuil du Bousquet (19 March 1714, in Brest, France – 1 July 1782, in Bourbonne-les-Bains), comte de Roquefeuil, was a French officer in the French Navy during the reigns of Louis XV and Louis XVI.

Promoted to chef d'escadre des Armées navales on 1 January 1761, at only 47 years old, and received the command of the ships and port at Brest, to which the king added command of Brest's town and castle and the Isle of Ushant on 25 March 1762 (three positions his father had already held).

He was promoted to vice-amiral on 6 April 1781 as well as Grand Croix of the Ordre royal et militaire de Saint-Louis.

Under his command, budgets were obtained from the king and his ministers and several powerful well-equipped ships were planned, launched and fitted out.

Little known by the public, he is considered by naval historians as one of the main men behind the organization and realization of Louis XV and Louis XVI's naval policy which allowed French and American allies to beat Great Britain in the American Revolutionary War.
