The Siege of Maastricht (1676) took place from 6 July to 27 August 1676 during the 1672 to 1678 Franco-Dutch War. A combined Dutch-Spanish army led by William III of Orange unsuccessfully tried to retake Maastricht, which the French had captured in 1673. It was eventually returned to the Dutch under the terms of the 1678 Treaty of Nijmegen.
