Duke's Cut is a short waterway in Oxfordshire, England, which connects the Oxford Canal with the River Thames via the Wolvercote Mill Stream.

The Duchy of Marlborough had owned Wolvercote paper mill since 1720, and much of the surrounding land belonged to their Blenheim Palace estate.

Mylne stated that this floodgate was of poor seal and water easily flowed into the canal at times the river was of a higher level.

[9] The cut had a towing path along its north bank, which ran to the Thames in the west and connected with that of the Oxford Canal.

[10] The towing path on the Oxford Canal crosses the cut by means of a brick arch bridge which also has Grade II listed status.
