Armenian Catholic Eparchy of Our Lady of Nareg in the United States of America and Canada (Latin: Eparchia Dominae Nostrae Naregensis) is an Armenian Catholic Church ecclesiastical territory or eparchy of the Catholic Church located in Glendale, California, United States and is immediately subject to the Holy See.

It was created by John Paul II on July 3, 1981, as the Apostolic Exarchate of United States of America and Canada for the Armenians.

The seat of the eparchy is St. Gregory the Illuminator Cathedral in Glendale, California.

[1] In 2012, the eparchy moved from New York City to Glendale, California.

[3] The church in New York was being sold and while the eparchy was offered a new church, the bishop decided to move the eparchy to Glendale since there were more Armenian Catholic families in the area than in New York.
