John Comyn II of Badenoch, the Black Comyn

John Comyn II, the Black Comyn (c. 1250–1302), was Lord of Badenoch and head of Scotland's most powerful baronial house. After Alexander III's death he became one of the six guardians for the infant queen Margaret, and later put forward a claim to the crown in the Great Cause.

He married Eleanor de Balliol, sister of King John Balliol, allying the two houses. He died in 1302 and was succeeded by his son John, the Red Comyn.
