He was the son of Piotr Opaliński and married Teresa Czarnkowska on 28 May 1634, with whom he had two sons: Piotr Adam Opaliński II and Jan Karol Opaliński and four daughters. Together with his brother Łukasz Opaliński he studied in the Lubrański Academy in Poznań, and later abroad at Louvain, Orléans and Padua. After returning to the Polish-Lithuanian Commonwealth with the position of a starost he became active on the political scene. In February 1632, he was elected a deputy at the election sejm which elected Władysław IV Vasa. In 1637, after his father's death, he became the Governor of Poznań. Opaliński opposed most of Władysław's military proposals, although he supported his idea of sea tariffs. In 1645 he led a diplomatic mission to Paris, where he was a proxy of king Władysław IV during his marriage to Marie Louise Gonzaga, whom he escorted back to Poland afterwards. In 1647 Opaliński purchased the town of Sieraków from his brother Łukasz and, in 1650, opened the first modern school in Poland, using the didactic materials prepared by Jan Amos Komenski. A Catholic himself, Opaliński was critical of the zealous Society of Jesus and supported religious tolerance. He was a patron of writers, scientists and a bibliophiles. Opaliński was a lifelong political rival of starost Bogusław Leszczyński in Greater Poland. When in 1648 Poland elected John II Casimir as king, Opaliński joined the opposition. The king had few friends among the Polish nobility, as he openly sympathised with Austria and showed disregard and contempt for Sarmatism, which has become part of Polish culture. Due to this, thinking that John Casimir was too weak or for any other reasons, he encouraged King Charles X Gustav of Sweden to claim the Polish Crown. During the Swedish invasion Krzysztof Opaliński and Bogusław Leszczyński were tasked with defence of the Greater Poland province. Dissatisfied with policies of John Casimir, they decided to surrender together with their pospolite ruszenie to Charles Gustav at Ujście on 25 July 1655. Many other voivodes of other voivodeships followed their suit, especially Prince Janusz Radziwiłł in the Grand Duchy of Lithuania. Almost the entire country was overrun by the Swedes, before the Jasna Góra resistance and the Tyszowce Confederation which turned the tide against the Swedes. Opaliński died in 1655 at Włoszakowice at the age of 44. He was buried next to his father in the catacombs of a local church in Sieraków.
