German submarine U-2342 was a short-lived Type XXIII U-boat of Nazi Germany's Kriegsmarine during the Second World War. She was built at Hamburg during 1944 as a modern Type XXIII "Elektroboote", a small coastal class designed to strike ships along the coastlines of Britain and liberated Europe, particularly the English Channel, although none ever served there. U-2342 was placed under the command of Oblt.z.S.d.R. Berchtold Schad von Mittelbiberbach, a former senior non-commissioned officer, who received a field promotion in 1943. She was his first submarine experience.
