Krzysztof Mikołaj Radziwiłł

Prince Krzysztof Mikołaj Artur Radziwiłł (29 July 1898 – 24 March 1986) was a Polish translator and politician, descendant of the well-known aristocratic Radziwiłł family. He was a supporter of the Communist regime in Poland, which gained him the nickname Czerwony książę (lit. 'Red Prince').

Krzysztof was owner of Staszów estates and member of the Sejm in the Polish People's Republic.

His daughter Anna Radziwiłł broke with his politics, becoming a noted dissident and influential member of Solidarity.
