SS Kronprinzessin Cecilie was an ocean liner built in Stettin, Germany in 1906 for North German Lloyd that had the largest steam reciprocating machinery ever fitted in a ship. The last of four ships of the Kaiser class, she was also the last German ship to have been built with four funnels. She was engaged in transatlantic service between her home port of Bremen and New York until the outbreak of World War I.

Norddeutscher Lloyd was a German shipping company. It was founded by Hermann Henrich Meier and Eduard Crüsemann in Bremen on 20 February 1857. It developed into one of the most important German shipping companies of the late 19th and early 20th centuries, and was instrumental in the economic development of Bremen and Bremerhaven. On 1 September 1970, the company merged with Hamburg America Line (HAPAG) to form Hapag-Lloyd AG.
