Moniaive is a village in the south of Scotland in Dumfries and Galloway, near Thornhill. The name is from the Gaelic mon-adh-abh and means "Hill of Streams".

In the 17th century, Moniaive became the refuge for the Covenanters, a group of Presbyterian non-conformists who rebelled at having the Episcopalian religion forced on them by the last three Stuart kings, Charles I, Charles II and James I.
