Fred. Olsen Cruise Lines is a UK-based, Norwegian-owned cruise shipping line with three cruise ships. The company is owned by Bonheur and Ganger Rolf and is headquartered in Ipswich, Suffolk, in the United Kingdom. The company is part of the Fred. Olsen Group.

The company originated in Hvitsten, a small town on Oslofjord in Norway, in 1848 by three Olsen brothers, Fredrik Christian, Petter and Andras, who bought their first ships and began an international shipping company. The company is now into the fifth generation of the family and operates various companies skilled within the cruise and passenger shipping trade, as well as aviation, ships' crewing, ship building and offshore industries. The Fred. Olsen group also has business interests in the luxury hotel sector, estate management,^[1] property development and electronics companies.^[2]

In May 2006 Fred. Olsen Cruise Lines announced the purchase of a new vessel, Norwegian Crown, from Norwegian Cruise Line. Following delivery of the vessel in November 2007, she was dry-docked for refurbishment and lengthening, with a pre-built 30 metre centre section added. She was renamed Balmoral and entered service early in 2008. This was followed by the extension of Braemar in summer 2008. A new centre section was added, with new cabins and public rooms, increasing the size from 19,000 GT to 24,000 GT (approx).

In 2018 Fred. Olsen announced that a series of 600-passenger-newbuilts is planned and they are in negotiatings with shipyards, but those newbuilts were never ordered.^[3]

In July 2020, Fred. Olsen bought the former Holland America Line ships Amsterdam and Rotterdam for $37m^[4] and renamed them Bolette and Borealis respectively, they will be delivered in September 2020. They replaced the Boudicca and the Black Watch, which were retired in August 2020.^[5][6]

For most of the year, the ships are based in UK ports. A winter Caribbean fly-cruise programme on Braemar operates from Barbados.

Destinations include Northern Europe, the Baltic, the Mediterranean, the Adriatic, the Canary Islands, the Caribbean, Africa, Canada, the United States and South America^{[citation needed]}
