German submarine U-214, was a Type VIID mine-laying U-boat of Nazi Germany's Kriegsmarine during World War II.

Laid down on 5 October 1940 by Germaniawerft in Kiel, the boat was commissioned on 1 November 1941 with Kapitänleutnant Günther Reeder (Crew 35) in command.

[4] U-214's fourth patrol took her to the Caribbean Sea where she attacked the 4,426 GRT unescorted Polish merchant ship Paderewski with torpedoes 40 nautical miles (74 km; 46 mi) off Trinidad, before sinking her with gunfire.

[5] U-214's fifth patrol was cut short when she was attacked on 7 May 1943 by a British Halifax bomber of 58 Squadron RAF in the Bay of Biscay, after only three days at sea.

Günther Reeder was severely wounded, resulting in first Officer Oberleutnant zur See Rupprecht Stock (Crew IV/37) bringing the U-boat safely back to base.

There, on 20 June, the American 6,507 GRT merchant ship Santa Maria struck a mine laid by U-214 five nautical miles (9.3 km; 5.8 mi) west of Dakar, blowing off her bows.

While outbound on 9 September, 92 nautical miles (170 km; 106 mi) south-west of Santa Maria, Azores, she was attacked by an American Grumman TBF Avenger aircraft from the escort carrier Croatan (CVE-25).

The aircraft approached by radar and dropped four depth charges, but was damaged in the air intake and the bomb bay by the U-boat's flak.

U-214 headed north into the shallow waters of the English Channel on 11 June, under the command of the newly promoted Kapitänleutnant Stock, however she had no successes,[2] and the patrol was curtailed after the U-boat was attacked by a British B-24 Liberator of 224 Squadron, sustaining damage which forced her to return to Brest on 2 July.
