Westfield is a geographic parish in Kings County, New Brunswick, Canada.

[2] Prior to the 2023 governance reform, for governance purposes it was divided between the town of Grand Bay-Westfield and the local service district of the parish of Westfield,[3] both of which were members of the Fundy Regional Service Commission (FRSC).

Notable is that the names of Kings County's pre-1800 parishes all occur in both New Jersey and North Carolina.

In 1896 the boundary on the Long Reach side of the Kingston Peninsula was altered slightly.

[9][10][11] Parks, historic sites, and other noteworthy places at least partly within the parish.
