Allardville is a geographic parish in Gloucester County, New Brunswick, Canada,

It is divided for governance purposes into the town of Hautes-Terres in the east and the Chaleur rural district in the west. Hautes-Terres is a member of the Acadian Peninsula Regional Service Commission and the Chaleur RD is a member of the Chaleur RSC.

Prior to the 2023 governance reform, the Hautes-Terres portion formed the local service district of Saint-Sauveur, while the Chaleur RD portion formed the LSD of the parish of Allardville.

The parish was named in honour of Monsignor Jean-Joseph-Auguste Allard, who brought new settlers from the East Bathurst area in 1932.

Allardville was erected in 1947 from parts of Bathurst, Saint-Isidore, and Saumarez Parishes. This was the last new parish to be erected in New Brunswick.

Allardville Parish is bounded:

• on the west by the Canadian National Railway line;
• on the north by the southern line of two land grants south of Goodwin Mill Road, prolonged southwesterly to the CNR line and northeasterly to the Tracadie Game Management Area, then taking a right-angle turn to the rear line Tier 1 of the Allardville East Settlement, which runs along the north side of Route 160, before turning northeasterly and following the rear of Tier 1 and its prolongation to about midway between Redpine Brook and Lac St. Coeur;
• on the east by a line southerly from midway between Redpine Brook and Lac St. Coeur along the prolongation of grant lines until it strikes the rear of Range 5 of the Saint Isidore Settlement, which runs along the north side of a different section of Route 160, then along Range 5 to midway between Butte-d'Or Road and the dogleg of Route 160 connecting the sections in Tier 1 and Range 5, then southerly at a right angle along grant lines at the end of Saint Isidore Settlement and their prolongation to the prolongation of the rear line of Range 9 of the Saint Isidore Settlement, which runs along the south side of Rang 9 Road;
• on the south by the prolongation of the rear line of Range 9 southwesterly past the Little South Branch Big Tracadie River to the line between Blocks 3 and 4 of Range 9 of timberland, then at a right angle southerly to the Northumberland County line, then westerly along the county line to the CNR line.

The parish's two LSDs sat side-by-side, with the boundary running northwesterly along grant lines about 8.1 kilometres easterly of the junction of Route 134 and Route 160 and prolongated northwesterly and southeasterly to the parish line. Both LSDs assessed for street lighting and community & recreation services in addition to basic LSD services.

Saint-Sauveur (established 1985) was the eastern LSD, taking its name from its westernmost community. The population in 2016 was 673.

Allardville (established 1999) was the western LSD. This LSD actually extends north to included part of Bathurst Parish; census data does not profile the extended area. Allardville was formed by merging three previous entities:

• The parish of Allardville (established 1969) originally included the entire parish and allowed residents to assess for fire protection.
• Allardville Centre (established 1970) comprised about 650 hectares north and south of the junction of Route 134 and Route 160; it added street lighting to the area.
• Allardville Nord (established 1991) was an area with enhanced services that straddled the Allardville-Bathurst parish line, which added street lighting to the area.

Governance reforms planned for 2023 would move Saint-Sauveur to the Acadian Peninsula Regional Service Commission, where it would form a local government entity with the villages of Paquetville and Saint-Isidore and the LSDs of the parish of Paquetville and the parish of Saint-Isidore. Allardville would remain part of the Chaleur RSC and be included in its rural district. These reforms are scheduled to take effect in 2023.
