The Treaty of Breda was signed at the Dutch city of Breda, 31 July (Gregorian calendar), 1667, by England, the United Provinces (Netherlands), France, and Denmark–Norway.
 It brought a hasty end to the Second Anglo-Dutch War (1665–1667) in favour of the Dutch, as Louis XIV's forces began invading the Spanish Netherlands as part of the War of Devolution, but left many territorial disputes unresolved.
 It was thus a typical quick "uti possidetis" treaty.
 In the latter stages of the war, the Dutch had prevailed.
 Lieutenant-Admiral Michiel de Ruyter virtually controlled the seas around the south coast of England, following his successful Raid on the Medway, and his presence encouraged English commissioners to sue for peace quickly.
 Negotiations, which had been long protracted, and had actually begun in Breda before the raid, took only ten days to conclude after resumption of talks.

 Nyborg was the final major conflict of the Dano-Swedish War of 1658 to 1660.
