Friedrich Karl Ferdinand Freiherr von Müffling, nicknamed Weiss (12 June 1775 – 10 January 1851), was a Prussian Generalfeldmarschall[1] and military theorist.

[2] In 1799 Müffling contributed to a military dictionary edited by Lieutenant W. von Leipziger, and in the winter of 1802–1803, being then a subaltern, he was appointed to the newly formed general staff as quartermaster-lieutenant.

[2] In 1806 Müffling served under Hohenlohe, Karl August, Grand Duke of Saxe-Weimar-Eisenach, and Blücher, and was included in the capitulation of the latter's corps at Ratekau on 7 November 1806, the day after the Battle of Lübeck.

[3] His business qualities and common sense were greatly valued, though the temperamental differences between Müffling and Gneisenau often led to friction, especially as the former was in a measure the representative of the antiquated topographical school of strategists, to whom (rightly in the main) the disaster of the Battle of Jena was attributed.

He spent a part of his time on the Rhine in survey work, and was employed by King Frederick William III in various diplomatic missions.
