Prince Stanisław Herakliusz Lubomirski aka "Mirobulius Tassalinus" (1642–1702) was a Polish noble, politician, patron of the arts and writer.

Lubomirski was the son of Marshal and Hetman Jerzy Sebastian Lubomirski and Konstancja Ligęza. He was married to Zofia Opalińska, the daughter of Court Marshal Łukasz Opaliński, in 1669 and to Elżbieta Doenhoff in 1676.

He was Podstoli of the Crown from 1669, Court Marshal of the Crown from 1673, Grand Marshal of the Crown from 1676 and starost of Spisz.

Lubomirski fought in wars against Sweden and Hungary. He participated with his father in the siege of Toruń in 1658. He refused to join the rokosz of his father and try to mediate between the rokoszans and the king.

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

He performed numerous diplomatic missions to France, Italy and Spain. He was against the abdication of king Jan II Kazimierz in 1668. From 1667 he was frequently deputy for the Sejm.

Owing to his experience and authority, the Sejm session in 1670 was not broken like the two sessions before, which were aborted by a veto.

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.

He was variously talented. He became famous outside of Poland as the author of literary and scientific works. He wrote poems, plays and philosophical, religious and historical tracts. He was the founder and benefactor of schools and churches.

As Sejm Marshal he led the Election Sejm from May 2 to June 19, 1669 and the ordinary Sejm from September 9 to October 31, 1670 in Warsaw.
