Comyn, John, d. 1306, Scottish nobleman. He was called the Red Comyn, to distinguish him from his father, the Black Comyn. Aiding his uncle, John de Baliol, in the struggle against Edward I, he was for a time held hostage by the English. After the rout of the Scottish troops at Falkirk (1298), he was appointed one of the guardians of the realm. He renewed the struggle with Edward, but surrendered in 1304 on condition that he could retain his lands. He was murdered at Dumfries by Robert the Bruce (later Robert I), probably because Robert feared him as a rival claimant to the throne. The name also appears as Cumming.
