German submarine U-2336 was a Type XXIII U-boat of Nazi Germany's Kriegsmarine during World War II.

Despite her short time in service, U-2336 is known for sinking the last two Allied merchant ships lost to a submarine in the war, when she torpedoed and sank the freighters Avondale Park and Sneland I off the Isle of May inside the Firth of Forth.

On 7 May 1945, U-2336 sank the last Allied merchant ships to be lost to a German submarine in the war, when she torpedoed the freighters Avondale Park and Sneland I (in order) off the Isle of May inside the Firth of Forth.

[7][8] Sneland I exploded as soon as it was hit and sank two minutes later, killing seven crew members, including the captain.

Avondale Park lost two crew members, with the rest entering a lifeboat or jumping into the sea.

[1] U-2336 was taken to Lisahally, United Kingdom on 21 June 1945 to take part in Operation Deadlight where she was sunk on 3 January 1946 by gunfire from the British destroyer HMS Offa.
