Lev Gillet (born Louis Gillett; 8 August 1893 - 29 March 1980) was an archimandrite of the Eastern Orthodox Church.
At this period he spent some time in the Benedictine house at Farnborough in Britain, and studying theology in Rome.
Attracted by Eastern Christianity, he became acquainted with Dom Lambert Baudouin (who later founded the bi-ritual communities at Amay and Chevetogne) and Metropolitan bishop Andriy Sheptytsky of the Ukrainian Greek Catholic Church in Galicia and pronounced his final vows as Lev in 1925 at the Studite monastery of Univ Lavra in Galicia.
At first he worked in various capacities - as warden of a boys' hostel, as a lecturer in the Quaker college in Birmingham, and serving the Society of Christians and Jews.
He remained in Britain until his death in 1980, going on many journeys abroad, in particular to France, Switzerland and Lebanon, where he took part in the spiritual revival of Antiochian Orthodoxy.
