Manafon is one of the smallest communities in Montgomeryshire, both geographically and in electorate.

It lies at the heart of Montgomeryshire, and is defined by the valley of the middle length of the river Rhiew.

The community has two main villages within about a mile of one another, Manafon and New Mills. The remainder of the population lives in scattered farms and dwellings and in the small rural settlement of The Green.
