Ludwig Matthias Nathanael Gottlieb von Brauchitsch (1757–1827)[1] was an aristocratic Prussian lieutenant general who fought in the Napoleonic Wars and was a recipient of the Pour le Mérite.

He was the son of a Prussian captain of artillery, Mathias Friedrich von Brauchitsch (1712 - 1757), and his wife Marie Magdalene Elisabeth (1736 - 1766), born in Oertzen.

For his service during the defense of Danzig in 1807 during the War of the Fourth Coalition, he received on in 1807 Frederick William III's Pour le Mérite.

He participated in the 1813 War of Liberation, in the organization of the country's storm against Napoleon's army, with the rank of lieutenant-general.

Brauchitsch married Wilhelmine Sophie Charlotte Luise in 1782, the sister of General Field Marshal Friedrich von Kleist.
