Christopher Kasparek (born 1945) is a writer and a translator from Polish into English.

Born in Edinburgh, Scotland, to Polish Armed Forces veterans of World War II, he lived several years in London, England, before moving with his family in 1951 to the U.S.A. He is a 1966 graduate of the University of California, Berkeley, where he studied Polish literature with the 1980 Nobel laureate Czesław Miłosz. In 1978 he received a medical degree from Warsaw Medical School , in Poland.

Kasparek has edited and translated books by the renowned historian of philosophy, Władysław Tatarkiewicz (On Perfection, 1979; A History of Six Ideas, 1980); the prominent military historian Władysław Kozaczuk (Enigma, 1984: the "Bible" on the Polish foundations of World War II Enigma decryption); Poland's greatest novelist, Bolesław Prus (Pharaoh, 2nd, revised edition, 2001); and other writers. A short but very demanding translation was his English version of Poland's Constitution of May 3, 1791 (c. 1985), since republished in numerous outlets, and available (corrected and augmented with the Free Royal Cities Act) on Wikisource. His translations of verse include selected Fables and Parables by Ignacy Krasicki.

Kasparek has made notable contributions to the history of Enigma decryption and has published ground-breaking papers on Bolesław Prus and his novel Pharaoh.
