Klaus Dönitz (13 May 1920 - 13 May 1944) was a German naval officer. He was the eldest of two sons of Admiral Karl Dönitz. When his younger brother Peter was killed in the sinking of U-954 on 19 May 1943, Klaus was allowed to withdraw from active service to begin training as a naval doctor. However, he was killed on the E-boat S-141 whilst accompanying it on a raid on Selsey, during which it was sunk by the French ship La Combattante. He was buried in the park of the Column of the Grande Armée.
