Bogislav Friedrich Emanuel Graf Tauentzien von Wittenberg (15 September 1760 – 20 February 1824) was a Prussian general of the Napoleonic Wars.

Shortly before the Battle of Saalfeld, a French corps under Marshal Bernadotte defeated Tauentzien's detachment of 9,000 men at Schleiz.

Tauentzien capably organized the retreat to Mittel-Pöllnitz so his troops could rejoin the main Prussian army.

As Generalleutnant, he commanded the Brandenburg Brigade after the Treaties of Tilsit and participated in the reorganization of the defeated Prussian army.

In 1813, Tauentzien was named Military Governor between the Oder and the Vistula Rivers, and he succeeded in the siege of Stettin.

Generalleutnant Leopold Wilhelm von Dobschütz led the capture of Wittenberg on the night of 13–14 January 1814, but acclaim for the victory went to his superior, Tauentzien, who was granted the honorary title "von Wittenberg", a coat of arms, and, on 26 January, the Grand Cross of the Iron Cross.

Before the August 1919 abolition of nobility as a legal class, titles preceded the full name when given (Graf Helmuth James von Moltke).
