Spirit of Adventure is a cruise ship operated by Saga Cruises and constructed by Meyer Werft in Papenburg, Germany. As Saga's second new-build vessel, she was originally considered as an option in the cruise line's pursuit to renew its fleet, but the company finalised the order in 2017 after seeing rising profits in its travel business following the announcement of her sister ship, Spirit of Discovery. Her keel was laid on 3 June 2019 and she was delivered on 29 September 2020, but in response to travel restrictions caused by the COVID-19 pandemic, the inaugural cruise was continuously postponed until she officially debuted on 26 July 2021.
