Michał Kazimierz Ogiński (c. 1728 – c. 1800) was a Polish nobleman, politician, musician, composer and military officer.

He began his political career at the age of 18, when he became the Field Writer of Lithuania, a mid-level position in the administration of the State.

He helped to establish the Pińsk–Volhynia road, the arsenal in Vilnius, and the Oginski Canal, which joined the watersheds of the Neman and Dnieper rivers (1765-1784).

At his court in Słonim he held two theater groups (Italian and Polish), a printing house and orchestra.

He was among two Polish scholars (alongside Jan Szczepan Kurdwanowski) who contributed to the French Encyclopédie.
