Costa Fascinosa is a Concordia-class cruise ship that was ordered in October 2007 for Costa Crociere. Based on the Concordia-class design, Costa Fascinosa was constructed by Fincantieri's Marghera shipyard in Venice. Part of a five-ship expansion of the Costa Crociere fleet, the vessel entered service on 6 May 2012. She was Costa Crociere's flagship until Costa Diadema entered service.

The Concordia Class is a class of cruise ships that are operated by Costa Cruises and Carnival Cruise Lines, subsidiaries of Carnival Corporation & plc.
