Inner Harbor () is a small harbor in the Melchior Islands, Palmer Archipelago, formed by the semi-circular arrangement of Lambda, Epsilon, Alpha and Delta Islands. The descriptive name was probably given by DI personnel who roughly surveyed the harbor in 1927. It was resurveyed by Argentine expeditions in 1942, 1943 and 1948.
