Prince Krzysztof Mikołaj Radziwiłł, nicknamed The Thunderbolt (Lithuanian: Kristupas (Mikalojus) Radvila "Perkūnas", 1547–1603) was a Reichsfürst of the Holy Roman Empire and a member of the nobility of the Polish-Lithuanian Commonwealth.

He was Cup-bearer of Lithuania from 1569, Field Hetman of Lithuania from 1572, Castellan of Trakai, Deputy Chancellor of Lithuania from 1579, Voivode of Vilnius Voivodeship from 1584, Great Lithuanian Hetman from 1589, and Starost.

Krzysztof Mikołaj Radziwiłł was one of the most talented commanders in the service of Polish–Lithuanian Commonwealth during the wars against Muscovy and Sweden, and won the Battle of Kokenhausen. His achievements combined with his powerful Radziwiłł family backing helped him rise to his various voivode and starost offices and further increased his family's wealth.

Like his father, brother, and nephew he was an ardent Calvinist, and an adherent of the Polish Reformed Church, and defended it against the rise of the Counter-Reformation.

Radziwiłł family coat of arms: Trąby. In the Holy Roman Empire, the Trąby coat of arms was situated in the center of a Black Eagle in a golden Shield.
