SS Prinz Friedrich Wilhelm was an ocean liner for North German Lloyd (NDL) from her launch in 1907 until the end of World War I. After the war, she briefly served as USS Prinz Friedrich Wilhelm (ID-4063) for the United States Navy returning American troops from France. The vessel was first chartered—and later purchased outright—by Canadian Pacific Steamships (CP) and operated under the names Empress of China, Empress of India, Montlaurier, Monteith, and Montnairn. She was scrapped in 1929.
