Henry of Scotland, 3rd Earl of Huntingdon (1114-1152) was a Prince of Scotland, of the House of Dunkeld, and an English peer. He was the son of King David I of Scotland and Maud, 2nd Countess of Huntingdon, and was named after his uncle, King Henry I of England. He had three sons, two of whom became King of Scotland, and a third whose descendents were to prove critical in the later days of the Scottish royal house.

Henry married Ada de Warenne, the daughter of William de Warenne, 2nd Earl of Surrey, and Elizabeth de Vermandois. Their children were:
1. Isabella of Huntingdon, married Robert de Ros, Baron Ros of Wark.
2. Ada of Huntingdon (1139 – 1206), married Floris III, Count of Holland.
3. Margaret of Huntingdon (1140 – 1201), married
1. Conan IV, Duke of Brittany;
2. Humphrey de Bohun.
4. Malcolm IV of Scotland.
5. William I of Scotland.
6. David of Scotland, 8th Earl of Huntingdon.
7. Matilda of Huntingdon, born and died 1152.

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 his title passed to his half-brother Simon of St Liz.
