Polar Star Expeditions was a specialty adventure cruise company owned by Karlsen Shipping Company Ltd. out of Halifax, Nova Scotia, Canada. In 2001, Polar Star began operating a single expedition cruise ship, MV Polar Star, a 87-metre (284 ft) converted Swedish icebreaker with 105 berths. The company conducted cruises mainly in the northern and southern polar and sub-polar regions. Polar Star Expeditions did not have an easy time of it. In 2010, its only vessel lost one of its engines and had to operate part of that season on just one. Then in January 2011, the vessel suffered serious grounding damage in the Antarctic, which led to the failure of the parent company.
