In the German Kriegsmarine of the Second World War, Generaladmiral was a rank senior to an Admiral, but junior to a Grand Admiral. Generaladmiral was a four-star Admiral rank, as in the traditional German ranking system until World War II an Admiral is equivalent to a British or American Vice Admiral.
The sleeve insignia for a Generaladmiral was the same as that of a regular Admiral, being a thick rank stripe below three regular stripes ("Kolbenringe" in German naval parlance). Generaladmirals wore a third pip on their shoulder boards to differentiate them from regular Admirals. The German Army and Air Force equivalent of Generaladmiral was the rank Colonel General (Generaloberst).
In 1943, a directive was issued that should the Oberbefehlshaber der Kriegsmarine (Commander of the Navy) hold the rank of Generaladmiral, he would wear the sleeve insignia of a grand admiral, but the shoulder boards of a Generaladmiral.
A similar practice was used in the German Army, allowing Colonel Generals to wear four pips on the shoulder board when engaged in duties befitting a field marshal.
The rank of Generaladmiral was first given to the future Grand Admiral Erich Raeder on 20 April1936.
Other holders of the rank were:
| • | Conrad Albrecht, | 1 April 1939, |
| • | Alfred Saalwächter, | 1 January 1940, |
| • | Rolf Carls, | 19 July 1940, |

| • | Walter Warzecha, | 1 March 1944, |
| • | Oskar Kummetz, | 16 September 1944, |
| • | Hans-Georg von Friedeburg, | 1 May 1945. |
It is interesting to note that Karl Dönitz was promoted to Grand Admiral without becoming a Generaladmiral first.
There were only nine holders of this rank:
General Admiral rank was abolished with the fall of the Empire and was not revived when rank distinctions were reintroduced during 1935-40. Admiral of the Fleet of the Soviet Union can be considered as a modern equivalent.
