A positive electrode for a lithium-sulfur battery and a lithium-sulfur battery including the same have a positive electrode that includes a positive active material, a conductor, an organic binder, and an additive. The positive active material includes at least one selected from elemental sulfur, a sulfur-based compound, or a mixture thereof. The additive includes a polymer having at least one amino nitrogen group in main chains or side chains.
