Vital Joachim Chamorin was a French general officer during the Napoleonic Wars. He enlisted as a private soldier in the French Royal Army and was commissioned as an infantry officer after the French Revolution. Chamorin was wounded at the 1794 Battle of Boulou and afterwards became an aide-de-camp, having two horses shot from under him at the 1800 Battle of Marengo. He became a cavalry officer in December 1800 and was appointed to command the 26th Dragoon Regiment in 1811. In the Peninsular War he was commended for his actions at the 28 March 1809 Battle of Medellín, but a recommendation for his promotion to general was not approved. After a further commendation for his actions on 11 February 1811, he was promoted to brigade general on 5 March. He was killed in action with British cavalry shortly afterwards at the Battle of Campo Maior.
