Costa Serena is a Concordia-class cruise ship for the Italian cruise line, Costa Crociere. The name Serena was intended to symbolize harmony and serenity.

Costa Serena was constructed by Fincantieri in Sestri Ponente. She had an older sister ship, Costa Concordia, launched in 2005. The ship, along with her three active sisters, was the largest and longest in the Costa Crociere fleet until being surpassed by the Costa Diadema in 2014.
