Mikołaj Struś (1577–1627) (Korczak coat of arms) was a Colonel of the Polish Army, a starosta and commandant of the Polish-Lithuanian garrison in the occupied Moscow Kremlin.
In the following years, he took part in a number of wars and military conflicts in eastern areas of the Polish–Lithuanian Commonwealth, as well as in Moldavia, Livonia and the Tsardom of Russia.
In the spring of 1612, together with 1000 infantry and 3000 cavalry, Strus joined forces of Lithuanian Hetman Jan Karol Chodkiewicz, which was sent to reinforce Commonwealth garrison of the Moscow Kremlin.
He was released on 10 June 1619, half a year after the Truce of Deulino, and immediately rejoined the Commonwealth army, fighting in the Battle of Cecora (19 September 1620).
Mikolaj Strus owned the towns of Probuzna and Strusow, located near Trembowla (today part of Ukraine), and the villages of Touste and Hrynkowce in Halych Land.
