Prince Michał Kazimierz Radziwiłł (1625-1680) was a Polish noble and magnate. He is sometimes referred to as the first Michał Kazimierz Radziwiłł, to distinguish him from the other member of his family to use the name.

He held the following titles: Ordynat of Nieśwież, stolnik of Lithuania (since 1652), krajczy of Lithuania (since 1653), podczaszy of Lithuania (since 1656), castellan of Wilno (since 1661), voivod of the Wilno Voivodship (since 1667), Deputy Chancellor of Lithuania (1668) and Field Hetman of Lithuania. He was also a starost of Upita, Przemyśl, Człuchów, Kamieniec, Chojnice, Lida, Telsze, Rabsztyn, Choteń, Homel, Ostra, Gulbin, and several other towns in the Polish-Lithuanian Commonwealth.

Between May 2 and July 18, 1661, he served as the Marshal of the ordinary Sejm held in Warsaw. He married Katarzyna Sobieska, the sister of the King of Poland Jan III Sobieski on June 16, 1658.

Unlike his cousins, the traitors Janusz Radziwiłł and Bogusław Radziwiłł, he was one of the members of the Radziwiłł family who valiantly fought in the defence of the Polish-Lithuanian Commonwealth during The Deluge.
