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

[1] The origin of the parish's name is uncertain, Greenwich being a placename in several of the Thirteen Colonies.

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

[11] In 1860 the mainland east of the Saint John River was included in the newly erected parish of Kars.

Recreational facilities were added to the assessment in 1995, with first aid and ambulance services removed at the same time.
