St. John Chrysostom Byzantine Catholic Church

St. John Chrysostom Byzantine Catholic Church is a Ruthenian Greek Catholic church in Pittsburgh, and is in full communion with the Roman Catholic Church. It primarily serves the descendants of immigrants of Rusyn descent and also descendents of immigrants from Slovakia, Ukraine, Belarus, Hungary, and Romania. The Divine Liturgy is chanted in English.

The church is located in the neighborhood of Four Mile Run, which is an isolated section of Greenfield at the bottom of Junction Hollow. Because it faces the heavily traveled Interstate 376, or Parkway East, the church has become a well-known architectural landmark for many commuters because its onion domes and Slavic-style crosses are easily seen from the Interstate.

The church is best known for having been the family church of the artist Andy Warhol.
