The Royal Game of Ur is a two-player strategy race board game of the tables family that was first played in ancient Mesopotamia during the early third millennium BC. The game was popular across the Middle East among people of all social strata, and boards for playing it have been found at locations as far away from Mesopotamia as Crete and Sri Lanka. One board, held by the British Museum, is dated to c. 2600 – c. 2400 BC, making it one of the oldest game boards in the world.
The Royal Game of Ur is sometimes equated to another ancient game which it closely resembles, the Game of Twenty Squares.
