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 to a ship. The last of four ships part of the kaiser class, she was also the last German ship to have been built with four funnels. She marked the end of the influence North German Lloyd had had in the Atlantic. She was engaged in transatlantic service between her homeport of Bremen and New York until the outbreak of World War I.
