The Koninklijke Nederlandse Stoomboot-Maatschappij (KNSM) (Royal Netherlands Steamship Company) was an Amsterdam-based shipping company that existed from 1856 to 1981. It was once the largest company in Amsterdam and one of the top five shipping lines in the Netherlands. The company operated mid-sized freighters that had limited passenger accommodations. At its peak in 1939, the company had 79 vessels. Of these, 48 were lost during World War II.
