Waterborough is a geographic parish in Queens County, New Brunswick, Canada.

Prior to the 2023 governance reform, for governance purposes it formed the local service district of the parish of Waterborough, which was a member of Capital Region Service Commission (RSC11).

The parish was said locally to describe the terrain. The original boundaries surrounded Grand Lake.

Waterborough was erected in 1786 as one of the county's original parishes. It completely surrounded Grand Lake and extended past the county line.

In 1827 Canning Parish was erected from Waterborough.

In 1852 part of Waterborough was included in the newly erected Cambridge Parish.

In 1855 Waterborough was expanded to the northwest, adding all of Chipman Parish southeast of Coal Creek.

In 1856 the boundary with Cambridge was adjusted.

In 1896 Waterborough was expanded northwest to reach the county line, taking part of Chipman.

Waterborough Parish is bounded:

• on the west by Grand Lake;
• on the northwest by a line running through the Northeast Arm of Grand Bay, then up Coal Creek past the mouth of the South Branch Coal Creek to the southeastern corner of a grant to Malcolm Carmichael at a stretch called the Round Turns, then northeasterly parallelling the southeastern line of the parish to the county line;
