Norwegian Cruise Line (NCL) is a company operating cruise ships, headquartered in unincorporated Miami-Dade County, Florida. It began operations in 1966 under the name Norwegian Caribbean Line.

The company is best known for its Freestyle Cruising concept, which means that there are no set times or seating arrangements for meals, nor is formal attire required. Norwegian Cruise Line has a sister company, NCL America. NCL itself is jointly owned by Star Cruises (who in turn are owned by the Genting Group based in Malaysia) and Apollo Management, with both companies owning 50% of NCL. Norwegian Cruise Line controls approximately 8% of the total worldwide share of the cruise market.
