Ivan Sleziuk

Ivan Slezyuk (, ; 14 January 1896 – 2 December 1973) was a Ukrainian Greek Catholic bishop and hieromartyr.

Life Slezyuk was born on 14 January 1896 in the village of Zhyvachiv, Austrian-Hungarian Empire (now in Ivano-Frankivsk Oblast, Ukraine). After graduating from the seminary in 1923, he was ordained a priest on 1923 by Bishop Hryhoriy Khomyshyn.

In April 1945, Khomyshyn consecrated him to the Episcopate as his coadjutor with the right of succession as a precaution in case Khomyshyn should be arrested. However, shortly thereafter on 2 June 1945, Slezyuk was arrested and deported for ten years to the labour camps in Vorkuta. In 1950, he was transferred to the labour camps in Mordovia. After his release on 15 November 1954, he returned to Stanislaviv. In 1962, he was arrested for the second time and imprisoned for five years in a camp of strict regimen. After his release on 30 November 1968, he had to go to the KGB for regular "talks." The last visit was two weeks before his death.
