Mesopotamia is a narrow ait (about 800 yards by 30 yards) that forms part of the University Parks in Oxford, England. It lies between the upper and lower levels of the River Cherwell which are partly interspersed with the Thames. The name Mesopotamia in Greek means "between the rivers", and is shared with an area between the Tigris and Euphrates rivers in present-day Iraq. The land was purchased by the University of Oxford during the expansion of the Oxford University Parks between 1860 and 1865. A footpath, Mesopotamia Walk, laid out in 1865 runs along the centre of the spur to Kings Mill.
