Hans Hermann Ludwig von Reuter (9 February 1869 – 18 December 1943) was a German admiral who commanded the High Seas Fleet when it was interned at Scapa Flow in the north of Scotland at the end of World War I.

[1] Two months after the outbreak of World War I, he was made captain of the battlecruiser SMS Derfflinger, which he also commanded during the Battle of Dogger Bank.

After the armistice that ended World War I, Konteradmiral von Reuter was requested to take command of the fleet that was to be interned at Scapa Flow until its final disposition would be decided at Versailles.

[1] As the final deadline neared for the German delegation to sign the Treaty of Versailles, Reuter anticipated that his ships would be handed over to the victorious Allies.

Nine German naval personnel were killed and 16 wounded by panicked guards either aboard their ships or on their lifeboats while rowing towards land (including Walter Schumann, the captain of SMS Markgraf).

The Treaty of Versailles forced Germany to drastically reduce the size of its navy leaving Reuter without a suitable command, given his rank and age.
