MS Rotterdam is a cruise ship operated by Holland America Line (HAL), a subsidiary of Carnival Corporation. Originally named Ryndam in development, she was renamed Rotterdam in July 2020 during construction to honor the name's legacy in the cruise line's history after six previous vessels in HAL's fleet bore the name. Rotterdam is the third of HAL's Pinnacle class in the fleet built by Italian shipbuilder Fincantieri and follows older sister ships Koningsdam (2016) and Nieuw Statendam (2018). Two years after the first steel was cut in March 2019 to commence construction, she was delivered in July 2021 and began operating in October 2021.
