Meskalamdug (𒈩𒌦𒄭, Meskalamdùg [mes-KALAM-du10] "hero of the good land"; fl. c. 2550 BC) was an early Sumerian ruler of the First Dynasty of Ur in the 26th century BCE. He does not appear in the Sumerian King List, but is known from a royal cylinder seal found in the Royal Cemetery at Ur, a royal bead inscription found in Mari, both mentioning him as King, and possibly his tomb, grave PG 755 at the Royal Cemetery at Ur.
It has been suggested that Puabi may have been his second queen.
