The Little Gruinard is a river in Wester Ross, Scotland which runs from the Fionn Loch into Gruinard Bay (famed for Gruinard Island). It lies within the Letterewe Estate, previously owned by Paul van Vlissingen, a Dutch businessman. It has a healthy run of Atlantic Salmon. The Little Gruinard has been a forerunner in the development of Catch and release fishing amongst Scottish salmon rivers.
