Diocese of the Northeast and Mid-Atlantic

The Diocese of the Northeast and Mid-Atlantic, with the Convocation of Eastern Canada, formerly known as the New York and Philadelphia Synod, is a founding jurisdiction of the Reformed Episcopal Church in 1873 and, more recently, a founding diocese of the Anglican Church in North America in 2009. It comprises 27 parishes, 26 of them in five American states – Maryland, Massachusetts, Pennsylvania, New Jersey and New York – and one in the Canadian province of Ontario. The current bishop is Bill Jenkins.

The Reformed Episcopal Church of the United States, founded in 1873, was originally organized into synods. The New York and Philadelphia Synod, one of the REC's founding synods, was renamed the Diocese of the Northeast and Mid-Atlantic when the nomenclature was changed in 1984.

As part of the Reformed Episcopal Church, the Diocese of the Northeast and Mid-Atlantic took part in the Anglican realignment movement in the United States, being one of the founding dioceses of the Anglican Church in North America, in 2009.

The diocese is home for the Reformed Episcopal Seminary in Oreland, Pennsylvania.
