SS Soesterberg was a Dutch-owned cargo steamship that was built in Belgium in 1927 and sunk by a U-boat in 1940 in the Battle of the Atlantic.

[1] Her owner was Stoomboot Mij Hillegersberg NV, who named her after the town of Soesterberg in the province of Utrecht, registered her in Amsterdam and appointed Vinke & Co of Rotterdam to manage her.

[1] The boilers fed a three-cylinder triple expansion steam engine that was rated at 214 NHP and drove a single screw.

[1] After the German invasion of the Netherlands in May 1940 Soesterberg remained in Allied service, making transatlantic crossings between Canada and Britain.

At 0122 hours on 19 October SC 7 was about 102 nautical miles (189 km) west by north of Barra Head, Outer Hebrides when German submarine U-101, commanded by Fritz Frauenheim, fired three bow torpedoes at the convoy.

[5] One of her stokers survived the sinking and was rescued by a lifeboat from the Empire Brigade, which had been sunk by Otto Kretschmer's U-99 in the same Wolfpack attack.
