Saint Procopius of Sázava (Latin: Procopius Sazavensis, Czech: Prokop Sázavský; died 25 March 1053) was a Czech Christian canon and hermit, who is venerated as a saint in the Eastern Orthodox Church and Roman Catholic church.

He was married and had a son, called Jimram (Emmeram), but later entered the Benedictine order, presumably at Břevnov Monastery, and eventually retired to the wilderness as a hermit, living in a cave on the banks of Sázava River, where over time he attracted a group of fellow hermits.

Local veneration of Procopius as a saint is recorded for the 12th century when the first biography Vita minor has been written.

Modern retellings of the saint's life were published by Czech poets Jaroslav Vrchlický and Vítězslav Nezval.

The "Cave of St. Procopius", the supposed site of his original hermitage, was discovered by Method Klement OSB in the 1940s.
