Antoine Marie Chamans, comte de Lavalette (14 October 1769 – 15 February 1830) was a French politician and general.

Born in Paris the same year as Napoleon Bonaparte, he spent the Revolution in the French Revolutionary Army, where he rose through the ranks to become an aide-de-camp to General Louis Baraguey d'Hilliers.

In 1796, after the Battle of the Bridge of Arcole, Baraguey d'Hilliers introduced his aide-de-camp to Napoleon, who was impressed enough to take him onto his personal staff and to entrust him with diplomatic missions.

He occupied a number of offices in the French Consulate and First Empire, most notably eleven years as Minister of Posts, during which he oversaw the covert monitoring of the mail of suspected Royalists.

Having escaped prison, Lavalette made his way to Great Britain with the assistance of a small group of British soldiers, amongst whom were Robert Wilson[1] and John Hely-Hutchinson.
