Job of Pochayiv was an Eastern Orthodox monk and saint who lived from approximately 1551 to 1651. Born Ivan Zalizo near Kolomyia, he entered monastic life at a young age, eventually serving as a hegumen at both the Dubno and Pochayiv monasteries. He was a significant theological writer who defended Orthodox dogmas against Protestantism and Uniatism. Known for his asceticism, he spent much of his later life as a hermit in a cave at Pochayiv, where he practiced constant prayer and strict discipline.
