The River Tiddy (Cornish: Teudhi)[1] is a small river in south-east Cornwall, England, United Kingdom. It is the main tributary of the River Lynher. The Tiddy rises near Pensilva and flows south east past the village of Tideford until it joins the Lynher just after passing St Germans. The name of Tideford derives from its location on the river, literally meaning "Ford on the River Tiddy".
