Prince Nikolai Ivanovich Svyatopolk-Mirsky (Russian: Николай Иванович Святополк-Мирский, Polish: Mikołaj Światopełk-Mirski; 29 July 1833 – 8 November 1898), of the Białynia clan, was a Russian cavalry general and politician.

Nikolai was born to the family of Tomasz Bogumił Jan Mirski, the ambassador of the semi-independent Kingdom of Poland to Russia.

Despite being a descendant of Polish szlachta he was brought up in Saint Petersburg and considered himself Russian.

Nikolai graduated from the Page Corps and later served in the Caucasus under Mikhail Semyonovich Vorontsov.

During the Russo-Turkish War, 1877-1878, he commanded a division that fought at the final Battle of Shipka Pass.
