Newcastle is a geographic parish in Northumberland County, New Brunswick, Canada. For governance purposes it is divided between the city of Miramichi and the Greater Miramichi rural district, with small border areas belonging to the incorporated rural communities of Alnwick (Bartibog area) and Miramichi River Valley (Chaplin Island Road), all of which are members of the Greater Miramichi Regional Service Commission, and the Eel Ground 2 and Metepenagiag Uta'nk Indian reserves, which are not part of the RSC. Prior to the 2023 governance reform, the parish was divided between Miramichi, the Indian reserves, and the local service districts of Lower Newcastle-Russellville and the parish of Newcastle.

Origin of name

Newcastle and Alnwick Parishes were erected simultaneously. Alnwick and Newcastle are the county town and largest city of historical Northumberland County, England. This may be the origin of the two parishes' names. Another possibility is that the parish was named in honour of the Duke of Newcastle, Prime Minister of Great Britain 1757–1762. The Duke had no obvious connection to the name Alnwick.

Evolution of boundaries

The original boundaries of Newcastle were Westmorland County on the south, a line due west from the northern tip of Portage Island on the north, and a north-south line through the mouth of Cains River on the west. In 1814 Northumberland County was completely reorganised and Newcastle took on a more recognisable shape. The boundary with Northesk was different, starting near the old courthouse and passing through the intersection of Newcastle Boulevard and Beaverbrook Road. In 1824 the boundary with Northesk was moved west to its modern starting point on Jones Cove. The direction of the boundary was also changed to run north instead of prolongation a grant line, which transferred a triangle of territory in the south to Newcastle and a triangle in the north to Northesk. In 1850 the boundary with Alnwick Parish was adjusted by running further up the Bartibog River before turning north.
