"Mirobulius Tassalinus" (4 March 1642 – 17 January 1702) was a Polish noble, politician, patron of the arts and writer.

He was married to Zofia Opalińska, the daughter of Court Marshal Łukasz Opaliński, in 1669 and to Elżbieta Doenhoff in 1676.

He was a proponent of the vivente rege elections and supporter of the politics of queen Ludwika Maria.

During the interregnum in 1673–1674 he supported the candidature of his friend, Jan Sobieski for the Polish throne.

In contrast to his father, he was free of private ambitions and always acted according to the interests of the Republic.
