'Catgut' was a British special forces raid on the island of Walcheren on the coast of the German-occupied Netherlands (1 November 1942).

The commandos landed in the village of Westkapelle in order to silence the German coastal batteries looking out over the Scheldt river estuary, and their success greatly facilitated the 'Infatuate' amphibious assault that paved the way to the German surrender of the island on 8 November.
