Alexander I (medieval Gaelic: Alaxandair mac Maíl Coluim; modern Gaelic: Alasdair mac Mhaol Chaluim; c. 1078 – 23 April 1124), posthumously nicknamed The Fierce, was the King of Scotland from 1107 to his death. He succeeded his brother, King Edgar, and his successor was his brother David. He was married to Sybilla of Normandy, an illegitimate daughter of Henry I of England.

Alexander was the fifth (some sources say fourth) son of Malcolm III and his wife Margaret of Wessex, grandniece of Edward the Confessor. Alexander was named after Pope Alexander II.

Alexander died in April 23 1124 at his court at Stirling; his brother David, probably the acknowledged heir since the death of Sybilla, succeeded him.
