The Norwegian America Line (Norwegian: Den Norske Amerikalinje), was a shipping line, originally an operator of ocean liners and cargo ships. Founded in 1910, the company ran a regular transatlantic service between Norway and the United States, and later included a route to East Africa as well. Primarily due to competition from air travel, transatlantic passenger voyages were slowly discontinued during the years. In 1980 the last two passenger liners were handed over into a new joint venture company (Norwegian American Cruises) with Leif Höegh & Co,and finally sold to Cunard Line in 1984.
