The Grenadiers à Cheval de la Garde Impériale (in English: Horse Grenadiers of the Imperial Guard) constituted a heavy cavalry regiment in the Consular, then Imperial Guard during the French Consulate and First French Empire respectively. They were the senior "Old Guard" cavalry regiment of the Imperial Guard and from 1806 were brigaded together with the Dragoons regiment of the Imperial Guard. They were arguably the best heavy cavalry regiment of their time.
