Dechmont Law is a hill in Livingston, West Lothian, Scotland. It lies around 700 yards south west of the village of Dechmont, where it derives its name. It is known locally as "Decky Hill" although these names are of far more recent provenance. It has also been known as "Dechmont Hill" (Law is Lowland Scots for "hill"). "Deer Hill" is another peak of the same hill, to the north east of the main peak.
