The 1654 Treaty of Westminster ended the First Anglo-Dutch War of 1652–1654. In it, the United Provinces recognized Oliver Cromwell's Navigation Acts, which required imports to the Commonwealth of England must be carried in English ships, or ships from the goods' origin.

Since the Navigation Acts had been the cause of the war, the treaty failed to resolve the dispute between the two countries and merely set the stage for the Second Anglo-Dutch War of 1665–1667.
