Ieperfest is a Belgian hardcore music festival held in Ypres. The summer edition of the festival was first held in September 1992, then annually each August from 1994 to 2018. Since 2019, the summer edition has been held annually each July. In February 2008, a winter edition was introduced, which was held annually in either February or March, until 2015. The winter edition has since been held sporadically, namely in 2018 and 2022. In 2012, during its 20th anniversary, Ieperfest became the longest-running hardcore festival in the world.
