German submarine U-2336 was a Type XXIII U-boat of Nazi Germany's Kriegsmarine during World War II. U-2336 had a very short career. She only conducted one war patrol and sank only three vessels, one of which was another German U-boat, during an accidental collision (U-2344). 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.
