Moncton is a geographic parish in Westmorland County, New Brunswick, Canada.

For governance purposes it is divided between the cities of Dieppe and Moncton; the town of Salisbury; the incorporated rural communities of Beausoleil and Maple Hills; the Metepenagiag 3 Urban Reserve, Metepenagiag 8 Urban Reserve, and Soegao 35 Indian reserves; and the Southeast rural district. The municipalities and the rural district are all members of the Southeast Regional Service Commission.

Prior to the 2023 governance reform, the local service district of the parish of Moncton, which included the special service areas of Calhoun Road, Greater Lakeburn, Irishtown, and Painsec Junction, included all of the parish outside Dieppe, Moncton, and Salisbury, and post-reform parts of Dieppe and Moncton.

The parish was named in honour of Robert Monckton, the British commander who captured Fort Beauséjour and oversaw the Expulsion of the Acadians.

Moncton was established in 1765 as Monckton Township in the province of Nova Scotia. The boundaries of the township were similar but not identical to the modern parish.

In 1786 Moncton Parish was erected as one of the province's original parishes, using the same boundaries as Monckton Township. The northeastern corner of the parish extended past the northern line of Westmorland County.

In 1835 all of Dorchester Parish north of the mouth of Fox Creek was transferred to Moncton.

In 1850 the western boundary was changed to match the prolongation of the eastern line of a block grant to Martin Gay and associates straddling the Petitcodiac River, adding part of Salisbury Parish.

In 1894 the boundary with Dorchester Parish was redefined to run along a magnetic bearing. The boundaries of the parish were made retroactive to its erection.

Moncton Parish is bounded:

• on the north by the Kent County line;
• on the east beginning on the county line about 150 metres east of Route 115, at the prolongation of the northeastern line of a grant to Martin Walsh on the north side of Route 134, then southeasterly along the prolongation, along the Walsh grant, which runs along the southwestern side of Marshall Road, and along the southeasterly prolongation about 12 kilometres past Route 134 to a point about 1.3 kilometres east of the Memramcook River;
• on the south by the prolongation of a line running south 83º 45' east from the southern side of the mouth of Fox Creek, then by the Petitcodiac River;
• on the west by the western line of the Second Tract granted to Joshua Geldart, about 200 metres upriver of the mouth of the Little River, and the north-northwesterly prolongation of the Geldart line to Kent County.
