The River Devon (Scottish Gaelic: Duibhe) is a tributary of the River Forth in Clackmannanshire, Scotland.
The source of the river is Blairdenon Hill in the Ochils at an altitude of 1,800 feet (550 m). Upper areas have been dammed, creating Upper Glendevon, Lower Glendevon and Castlehill reservoirs. The Devon then flows east and southeast through Glendevon, turning southwest at Crook of Devon and then continuing westwards, meandering across its flood plain along the foot of the Ochil Hills. It reaches the River Forth to the west of Alloa at the small village of Cambus.
The UK Centre for Ecology & Hydrology, (part of UK's Natural Environment Research Council, NERC) describes the catchment area thus: "Headwaters are steep; lower valley is broad and very flat. Bedrock extrusive igneous rocks, 50% overlain by superficial deposits. Land use arable in the valley; grassland in headwaters, some forest." The catchment covers an area of 181 km2.
During the Scottish Reformation, William Kirkcaldy destroyed the bridge at Tullibody in attempt to prevent French troops retreating to the Siege of Leith at the end of January 1560. However, the French took down the roof of Tullibody Kirk to bridge the Devon.
