Carnival Venezia is a Vista-class cruise ship operated by Carnival Cruise Line, a subsidiary of Carnival Corporation & plc. Originally intended to serve the Chinese market, she debuted as Costa Venezia for sister brand Costa Cruises in Shanghai on 18 May 2019.[5] At and with a capacity of 4,208 passengers, she became the largest ship commissioned for the Costa fleet upon her delivery.
In 2023, amid a corporate fleet reshuffling in the wake of the COVID-19 pandemic and its impact on the industry, Costa Venezia was transferred to Carnival under a new sub-brand named "Costa as Carnival" operating as "Carnival Fun Italian Style". The new concept was designed to integrate Costa Venezia and sister ship Costa Firenze into Carnival in a bid to boost domestic American capacity after the cruise line had sold numerous older vessels while Costa contended with operational challenges in its core markets. In March 2023, she was officially renamed Carnival Venezia during her pre-delivery renovation and debuted for Carnival the following May as the lead vessel for the new sub-fleet of Venice-class ships.
