SS Robin Moor was a United States cargo steamship that was built in 1919 and sunk by a U-boat in May 1941, several months before the US entered World War II. The U-boat allowed the passengers and crew to launch her lifeboats and abandon ship with no loss of life. However, the sinking of a neutral ship in an area considered until then to be relatively safe from U-boats, and the plight of her crew and passengers, caused a political incident in the United States.
