The Lennox (Scottish Gaelic: Leamhnachd, pronounced [ʎãũnəxɡ̊]) is a region of Scotland centred on the The Vale of Leven.
Lennox was not one of the so-called seven Provinces of Scotland, but as a district derived its name from the Gaelic rendering of the vale of the Leven, including the great lake of Loch "Leven" now known as Loch Lomond. It was styled Levenauchen or Levenachs, softened into Levenax or Lennax, signifying "the field of the smooth stream". The district embraced under this name contained the whole of the ancient sheriffdom of Dumbarton: the parishes of Rosneath, Arrochar, Row, Luss, Cardross, Bonhill, Dumbarton, Kilmaronock, New Kilpatrick, Old Kilpatrick, Baldernock, Buchanan, Drymen, Killearn, Balfron, Fintry, and Strathblane, with Campsie and Kilsyth, being all within the bounds ruled over by the Earls of Lennox.
