The 2011 World Championship of Ski Mountaineering (Italian: Campionato del Mondo di Scialpinismo 2011) were held instead of the originally 9th edition of the European Championships of Ski Mountaineering, why it was the first World Championship in an odd-numbered year, besides the Trofeo Mezzalama in 1975, which was the real first world championship of ski mountaineering. Instead, the 9th edition of the European championships was held in February 2012.
