The 3rd Algerian Infantry Division () was an infantry division of the French Army during the last half of the Second World War. The 3e DIA had one of the most successful combat records of any French Army division during the Second World War. It paid a high price for this distinction, suffering more than 3,000 soldiers killed in action between 1942 and 1945. It was considered by Marshal Juin and General de Monsabert as the "worthy heir" of the Legio III Augusta.
