Henry of Scotland (Eanric mac Dabíd, 1114 – 12 June 1152) was a Prince of Scotland, heir-apparent to the Kingdom of Alba. He was also the 3rd Earl of Northumberland and the 3rd Earl of the Honour of Huntingdon and Northampton.
He was the son of King David I of Scotland and Maud, 2nd Countess of Huntingdon. His maternal grandparents were Waltheof, Earl of Northumbria and Huntingdon, (beheaded 1075) and his spouse Judith of Lens.
Henry was named after his uncle, King Henry I of England, who had married his paternal aunt Edith of Scotland (the name Edith gallicised as Matilda after becoming Queen consort in 1100). He had three sons, two of whom became King of Scotland, and a third whose descendants were to prove critical in the later days of the Scottish royal house. He also had three daughters.
His eldest son became King of Scots as Malcolm IV in 1153. Henry's second son became king in 1165 on the death of his brother, reigning as William I. Both in their turn inherited the title of Earl of Huntingdon. His third son, David also became Earl of Huntingdon. It is from the 8th Earl that all Kings of Scotland after Margaret, Maid of Norway claim descent.
On Henry's death, the Earldom passed to his half-brother Simon II de Senlis.
