German submarine U-88 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II. She was laid down at the Flender Werke in Lübeck as yard number 292, launched on 16 August 1941 and commissioned on 15 October with Kapitänleutnant Heino Bohmann in command. She was a fairly successful boat, succeeding in sinking 12,304 GRT of Allied shipping in a career lasting just one year over three patrols.
