The Douglas Water (Scottish Gaelic: Dùghlas) is a river in Argyll in the southwest Scottish Highlands. It emerges from the northeastern end of the diminutive Loch Dubh-ghlas (56°12′07″N 5°12′48″W / 56.2019°N 5.2134°W) and flows northeastwards through Coire Dubh-ghlas, before turning east then southeast amongst extensive conifer plantations to the bridge which carries the A83 road over it. It then turns east at this point and flows into the tidal Loch Fyne (56°11′47″N 5°06′31″W / 56.1963°N 5.1086°W).
