Nikolay Alexeyevich Tuchkov (16 April 1765 – 30 October 1812, Yaroslavl) was a Russian general of the Russo-Swedish War (1788–1790), the suppression of the Kościuszko Uprising and the opposition to the French invasion of Russia.

The brother of Pavel & Alexander Tuchkov, Nikolay first came to note as a Major General commanding a Brigade of Gortchakov's wing under Korsakov in Switzerland, 1799, serving at the Second Battle of Zurich 25–26 September.

After hearing news of the defeat at Friedland on the 27th he abandoned Ostrolenka & retreated on Tykoczin, and was subsequently replaced by Tolstoi before the Treaty of Tilsit.

He fought at Smolensk 17 August, then with Württemberg was defeated by Michel Ney at Lubino[2] on the 19th, however, having sustained lesser losses against superior forces.

Stationed on the left flank at Borodino on 7 September, he was gravely wounded in the chest leading the Pavlovsky Grenadiers against Utitsa during a successful counterattack and died three weeks later.
