Jan Willem de Winter (23 March 1761 – 2 June 1812) was a Dutch naval officer who served in the French Revolutionary and Napoleonic Wars.

The new regime now utilized the experience he had gained as a naval officer by giving him the post of adjunct-general for the reorganization of the Batavian Navy.

He spared no efforts to strengthen it and improve its condition, and on 11 October 1797 he ventured upon an encounter off Camperdown with the British fleet under Admiral Adam Duncan.

De Winter enjoyed the confidence of Louis Bonaparte, then King of Holland, and, after the incorporation of the Netherlands in the French empire, in an equal degree of the emperor Napoleon.

[1] Napoleon gave De Winter the grand cross of the Legion of Honour and appointed him inspector general of the northern coasts, and in 1811, he placed him at the head of the fleet he had collected at Texel.
