The Yser Towers (Dutch: IJzertoren) are a monument complex near the Yser river at Diksmuide, West Flanders in Belgium. The first tower was built in 1928–30 to commemorate the Belgian soldiers killed on the surrounding Yser Front during World War I and as a monument to Christian pacifism. However, it subsequently became an important political symbol for the Flemish Movement and was destroyed in 1946 as a result of its association with Flemish nationalist collaboration in German-occupied Belgium in World War II. The current tower was rebuilt alongside the remains of the original and copied its design. It was finished in 1965. It remains a site of political significance to Flemish nationalists and is the center for their annual Yser Pilgrimage (IJzerbedevaart).
