The Mortier de 81mm léger long renforcé (LLR 81 mm) is a mortar used by the French Army. It is the latest iteration of the TDA 81 mm light mortar family, introduced in 1997.

Since then, three variants have been fielded: * the 81mm LC (Léger court, "light short"), with a 1.15-metre barrel; * the 81mm LL (Léger long, "light long"), with a 1.55-metre barrel; * the 81mm LLR (Léger long renforcé, "light long reinforced"), paratrooper version with a 1.55-metre barrel.
