The ship, which is being delivered in the first quarter of 2020, will be given the name following a competition between staff, agents and customers that saw 2,600 names submitted.
Once launched the 55,254 tonne oship will have capacity for 750 guests.
Regent Seven Seas Cruises president and chief executive Jason Montague said: “The naming of a ship is an important milestone in maritime tradition and it is my pleasure to announce that the name of Regent Seven Seas Cruises’ new ship to launch in 2020 is Seven Seas Splendor.
“The extraordinary demand for Seven Seas Explorer has reinforced our decision to expand our fleet and Seven Seas Splendor will offer guests a fifth option that will provide unforgettable experiences in the world’s most compelling destinations, with the incredibly high standards of luxury and service that lure guests back again and again.”
