Benwick is a village and civil parish in the Fenland district of Cambridgeshire, England in the historic Isle of Ely.

The River Nene (Old Course) (part of the Middle Level Navigations) passes through the village, which is thus accessible by boat from the inland waterways network in England.

H. C. Darby, in his Drainage of the Fens, records that in 1611 a scholar from the continent, toured the Isle of Ely, noting that the houses in Benwick were all surrounded by water, like islands, and the inhabitants were occupied with fishing and fowling.

[5] In 1774 the Earl of Orford remarked of Benwick that "the number of children crossing near a cottage and a school added much to the scene, in appearance much like the best Flemish Landscapes".

[6] In 1737, it was reported 'From March in the Isle of Ely we hear of a most audacious and uncommon Outrage committed on the 6th inst.

at Berwick, a small Village between March and Whittlesey, by a numerous Body of Irishmen, who having swarm'd in those Parts for Harvest-Work, upon a Quarrel with the Inhabitants they ravag'd and plunder'd the whole Town and the next Day they attempted the like at March (and) might probably have succeeded, had not Numbers from Whittlesey came opportunely to the Succour of the March-Men but after a sharp Engagement, wherein several were wounded on both Sides, the Irishmen were put to the Route, leaving behind them only five of their Companions, who were taken Prisoners and committed to Wisbech Goal'.

[11] Benwick is part of the parliamentary constituency of North East Cambridgeshire; the current Member of Parliament is Steve Barclay.

A Baptist chapel was first built in 1818 on land endowed from Gideon Gascoigne; at first just a preaching place as the church was not formed until 1858.
