The Institut Jeanne d'Arc, also Den Franske Skole, was a French-language Roman Catholic school at 74 Frederiksberg Allé in the Frederiksberg district of central Copenhagen, Denmark. Established in 1924, it was bombed by the Royal Air Force on 21 March 1945, during Operation Carthage, when pilots mistook the school for their actual target, which was roughly 1.6 km (1 mi) to the east-northeast. The bombing killed 86 children and 19 adults.
