Michał Tomasz Wiśniowiecki (31 May 1640 – 10 November 1673), also known as Michał Korybut Wiśniowiecki (Lithuanian: Mykolas Kaributas Višnioveckis), and under a regal name Michael I (Polish: Michał I; Lithuanian: Mykolas I), was the ruler of the Polish–Lithuanian Commonwealth as King of Poland and Grand Duke of Lithuania from 29 September 1669 until his death in 1673.
Michael was chosen partly because of the merit of his father, prince Jeremi Wiśniowiecki, a powerful border magnate who had helped suppress the rebellious Cossacks during the Khmelnytsky Uprising. After Michael's early death, these setbacks were reversed at the Battle of Khotyn in 1673 by his successor, John III Sobieski, who defeated an Austrian candidate in the election.
In 1670, Michael I was married to Eleonora Maria of Austria (1653–1697), daughter of Ferdinand III, Holy Roman Emperor, and his third wife Eleonora Gonzaga. They had one son, who died at birth.
