The Regiment of Mounted Grenadiers (Spanish: Regimiento de Granaderos a Caballo) is the name of two Argentine Army regiments of two different time periods: a historic regiment that operated from 1812 to 1826, and a modern cavalry unit that was organized in 1903. The second Regiment of Mounted Grenadiers was formed in 1903, and serves as the national ceremonial unit. It claims the original regiment of 1812 as its heritage, but has no direct link or lineage. As a unit, it has never been in combat, although ten members of the regiment were seconded to other units which fought in the Falklands.
