Holy Trinity Monastery is a male stavropegial monastery of the Russian Orthodox Church Outside of Russia (ROCOR), located near Jordanville, New York. Founded in 1930 by two Russian immigrants, it eventually became a main spiritual center of Russian Orthodoxy in the West. The monastery is well known for its publishing work and for the attached Holy Trinity Orthodox Seminary, which has educated many clergymen in ROCOR and other Orthodox jurisdictions. Due to their closeness to the hamlet, both the monastery and seminary are often simply referred to as Jordanville. The monastery is dedicated to the Holy Trinity, and its patronal feast day is Pentecost. The campus includes a museum that is open to the public.

A stauropegion, also spelled stavropegion, is a monastery or a parish which depends directly on the primate or on the Holy Synod of a particular Church, and which is not under the jurisdiction of the local bishop. The name comes from the Byzantine tradition of summoning the Patriarch to place a cross at the foundation of stauropegic monasteries or parochial churches.
