De Hoop (English: The Hope) is a smock mill in Holwerd, Friesland, Netherlands which was built in the 1730s and is working for trade.

[1] The earliest record of a windmill in Hollum is c1399, when the windrecht (English: right to wind) was mentioned on page 292 of the Zoenbrief en Accoord between Count Albrecht van Beieren and the Frisian people.

[2] The earliest record of a mill named De Hoop is that it was standing in 1711. when it was bought for ƒ2,540 by Jan and Jeppe Harmens from Antie Lammerts, widow of miller Oeble Sipkes.

In 1713, Jan Harmens sold his share of the mill to Nittert Siemens for ƒ1,170.

In 1721, Jeppe Harmens took over his father's mill at Lioessens and sold his share in De Hoop to Heert Pytters.

[2] The mill was then worked by his widow Nieske Kadijk until it was sold by auction at De Zwaan, Holwerd on 12 May 1839.

[2] On 26 March 1873, Hoekstra's wife Fokelina Kornelis Posthuma died, followed on 29 October 1873 by their daughter Trijntje.

[2] In December 1956, the Gemeente Westdongeradeel entered into negotiations with Hiddema with the aim of purchasing the mill for preservation.

In 1962, further negotiations were made, and millwright Jellema of Birdaard was asked to assess the costs of restoration of the mill building only.

[2] In 1980,[4] the internal machinery was restored and the mill was returned to working order at a cost of ƒ270,000.

In that year, ownership of De Hoop was transferred to Stichting Monumentenbehoud Dongeradeel.

The great spur wheel drives a pair of 1.40 metres (4 ft 7 in) diameter Cullen millstones via a lantern pinion stone nut which has 24 staves.

There are also two pairs of millstones used for producing pearl barley, each is driven via a lantern pinion stone nut which has 24 staves.
