Máel Coluim mac Domnaill (anglicised Malcolm I) (died 954) was king of Scots (before 943 – 954), becoming king when his cousin Causantín mac Áeda abdicated to become a monk. He was the son of Domnall mac Causantín.

Máel Coluim was probably born during his father's reign (889–900). By the 940s, he was no longer a young man, and may have become impatient in awaiting the throne. Willingly or not—the 11th-century Prophecy of Berchán, a verse history in the form of a supposed prophecy, states that it was not a voluntary decision that Constantine II abdicated in 943 and entered a monastery, leaving the kingdom to Máel Coluim.

Seven years later, the Chronicle of the Kings of Alba says:

[Malcolm I] plundered the English as far as the River Tees, and he seized a multitude of people and many herds of cattle: and the Scots called this the raid of Albidosorum, that is, Nainndisi. But others say that Constantine made this raid, asking of the king, Malcolm, that the kingship should be given to him for a week's time, so that he could visit the English. In fact, it was Malcolm who made the raid, but Constantine incited him, as I have said.

Woolf suggests that the association of Constantine with the raid is a late addition, one derived from a now-lost saga or poem.

He died in the shield wall next to his men. Máel Coluim would be the third in his immediate family to die violently, his father Donald II and grandfather Constantine I both having met similar fates 54 years earlier in 900 and 77 years earlier in 877 respectively.

In 945, Edmund I of England, having expelled Amlaíb Cuaran (Olaf Sihtricsson) from Northumbria, devastated Cumbria and blinded two sons of Domnall mac Eógain, king of Strathclyde. It is said that he then "let" or "commended" Strathclyde to Máel Coluim in return for an alliance. What is to be understood by "let" or "commended" is unclear, but it may well mean that Máel Coluim had been the overlord of Strathclyde and that Edmund recognised this while taking lands in southern Cumbria for himself.
