Hillsborough is a geographic parish in eastern Albert County, New Brunswick, Canada.

[16] The northern boundary was moved slightly south in 1850 to its modern starting point.

The village of Hillsborough is on the Petitcodiac River, from south of Weldon Creek to north of Christopher Lane; the inland boundary is irregular, based partly on grant lines and partly on property lines of the late 1960s.

[19] The LSD was established on 23 November 1966 to assess for fire protection[20] following the abolition of rural governments by the new Municipalities Act.
