Father Cleopa Ilie (Romanian pronunciation: [kleˈopa iˈli.e]; 10 April 1912 – 2 December 1998) was an abbot of the Sihastria Monastery. He was a well-known spiritual representative of the Romanian Orthodox Church.
Cleopa Ilie (lay name: Constantin) was born in Sulița, Botoșani to a family of peasants. He was the fifth of ten children born to Alexandru Ilie. He attended the primary school in his village. Afterwards he was an apprentice for three years to the monk Paisie Olaru, who lived in seclusion at the Cozancea hermitage.
Together with his elder brother, Vasile, Ilie joined the community at Sihastria hermitage in December 1929. In 1935, he joined the army in the town of Botoșani, but returned a year later to the hermitage, where he was anointed a monk on 2 August 1937, taking the name "Cleopa" (i.e. "guide") at his baptism. In June 1942, he was appointed to hegumen deputy because of abbot Ioanichie Moroi's poor health.
On 27 December 1944, he was ordained a hierodeacon (deacon-monk) and on 23 January 1945 a hieromonk (priest-monk) by the archbishop Galaction Cordun, abbot of the Neamţ Monastery at the time. Afterwards he was officially appointed hegumen of the Sihastria Hermitage.
In 1947, the hermitage became a monastery and vice-archimandrite Cleopa Ilie became archimandrite on approval of Patriarch Nicodim. Because the Communist secret service was looking for him in 1948, he disappeared into the woods surrounding the monastery, staying there for six months. On 30 August 1949, he was appointed abbot of the Slatina Monastery in Suceava county, where he joined 30 other monks from the Sihastria Monastery community as a result of Patriarch Justinian's decision.
