Bruges Matins, the nocturnal massacre of the French garrison in Bruges by members of the local Flemish militia.

The Matins of Bruges was the nocturnal massacre of the French garrison in Bruges and their Leliaards supporters, a political faction in favour of French rule, on 18 May 1302 by the members of the local Flemish militia. It has been named "Matins" in analogy to the Sicilian Vespers of 1282. The revolt led to the Battle of the Golden Spurs, which saw the Flemish militia defeat French troops on 11 July 1302.

Bruges is the capital and largest city of the province of West Flanders, in the Flemish Region of Belgium. It is in the northwest of the country, and is the sixth most populous city in the country.

Flanders is the Dutch-speaking northern portion of Belgium and one of the communities, regions and language areas of Belgium. However, there are several overlapping definitions, including ones related to culture, language, politics, and history, and sometimes involving neighbouring countries. The demonym associated with Flanders is Fleming, while the corresponding adjective is Flemish, which can also refer to the collective of Dutch dialects spoken in that area, or more generally the Belgian variant of Standard Dutch.
