Monkey Marsh Lock is a lock on the Kennet and Avon Canal, at Thatcham, Berkshire, England.

Monkey Marsh Lock was built between 1718 and 1723 under the supervision of the engineer John Hore of Newbury. The canal is administered by Canal & River Trust. The lock has a rise/fall of 8 ft 8 in (2.64 m).[1]

One of only two remaining working examples of turf sided locks on the canal (the other being Garston Lock[2]), Monkey Marsh Lock is listed as an ancient monument by English Heritage [3][4]
