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

Prior to the 2023 governance reform, for governance purposes it was divided between the village of Cambridge-Narrows and the local service district of the parish of Wickham, both of which were members of Kings Regional Service Commission (RSC8).

The parish may have been named for Wickham, Hampshire, near the birthplace of William Spry. Among Spry's numerous pre-Loyalist grants was one of 3000 acres in the Wickham area in 1774.

Wickham was erected in 1786 as one of the county's original parish. The parish surrounded Washademoak Lake and extended past the county line.

In 1839 the northeastern part of Wickham was erected as Johnston Parish.

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

In 1895 the eastern half of Long Island was transferred from Hampstead Parish.
