The Ecclesia Gnostica (Latin for The Gnostic Church) is a gnostic church founded in United States under the name Pre-Nicene Gnostic Catholic Church in 1959 after influence from England.

It has a sister organization named the Gnostic Society, which also run the gnosis.org website on gnosticism. This organization is intended for studies of gnosticism, not religious services.

The regionary and only bishop of the church is Stephan A. Hoeller, a notable gnostic who has written extensively on gnosticism and jungian psychology.
