The Jed Water is a river and a tributary of the River Teviot in the Borders region of Scotland.
In total Jed Water is over 20 miles (32 km) long, it flows into the Teviot near Jedfoot Bridge (grid reference NT660243) from a source in the Cheviot Hills.
The river in past times was the main source of water for the monks living in Jedburgh Abbey. It also powered a watermill in the town of Jedburgh although this no longer exists. It gives its name to Jedburgh and Jedforest.
The name Jed is of obscure origin. James has suggested that it may derive from Proto-Indo-European *wei(h1)- d- 'a bend, something curved or twisted'. He also notes that Scots Gedde- in Jedburgh may have been adopted from Cumbric gwï:δ 'a wood', and that the river name may be a back-formation.
