Ada de Warenne (or Adeline de Varenne) (c. 1120 – 1178) was the Anglo-Norman wife of Henry of Scotland, Earl of Northumbria and Earl of Huntingdon. She was the daughter of William de Warenne, 2nd Earl of Surrey by Elizabeth of Vermandois, and a great-granddaughter of Henry I of France. She became mother to two Kings of Scots, Malcolm the Maiden and William the Lion.

Ada and Henry were married in England in 1139. They had seven children:

As part of her marriage settlement, the new Countess Ada was granted the privileges of Haddington, amongst others in East Lothian. Previously the seat of a thanage Haddington is said to be the first Royal burgh in Scotland, created by Countess Ada's father-in-law, David I of Scotland, who held it along with the church and a mill.

In close succession both her husband and King David died, in 1152 and 1153 respectively. Following the death of Henry, who was buried at Kelso Abbey, King David arranged for his grandson to succeed him, and at Scone on 27 May 1153, the twelve-year-old was declared Malcolm IV, King of Scots. Following his coronation, Malcolm installed his brother William as Earl of Northumbria (although this county was "restored" to King Henry II of England by Malcolm in 1157), and the young dowager-Countess retired to her lands at Haddington.
