Hadden is a hamlet in Scotland near Kelso, and is now part of the Scottish Borders district. "Hadden is an inhabited place in the parish of Sprouston."

The name "Hadden" has several variants. A common variant is that the name is a corruption of "Half-Dane", referring to the children born nine months after Viking raids.

"Hadden, an ancient village, now reduced to a single farmhouse, in Sprouston parish, NE Roxburghshire, 7 furlongs E of the English Border, 5 furlongs SSW of Carham station, and 5 miles ENE of Kelso. In olden days it was a frequent meeting-place of Scottish and English commissioners, to adjust boundaries and to settle disputes. Hadden Rig, a ridge of elevated land that runs through the middle of the parish, and culminates at an altitude of 541 feet, was the scene in 1540 of the defeat of 3000 mounted English troops by a Scotch force." Ordnance Survey, sh. 26, 1864.

"Hadden has references dating back to the early thirteenth century. It is situated one mile west of the ‘Border Line’ which was fixed in 1222 and, at that time, Hadden is referred to as being ‘a place of considerable importance’. Hadden was also a meeting place for the Lord Warden of the Marches, with one meeting of particular importance having been held in 1397 to redress cross border violations. Over the centuries there have been numerous battles over the Border marches. On 24 August 1542, following ruptures between James V and Henry VIII, the Scots are reported to have defeated an English force during a hard contest at the battle of Hadden Rig. The Scots, under Earl of Moray, defeated the English led by Sir Robert Bowes (lawyer), and took him and 600 of his men prisoner. Nearby is Haddon Rig, where the Battle of Haddon Rig, also known as the "Battle of Hadden-Rig", was fought."

Also nearby named places are "Hadden Woods" and "Hadden Farm". This farm is by a minor road between Kerchesters and Nottylees. "Hadden Farm" is listed in the Acts of Alexander III of Scotland, in 1278, where he gave to Eymer de Hadden 22 marks (merkes) for land in Roxburghshire. This was later presented to Parliament in 1305 where Hadden showed that the king had paid him the funds annually.
