Duncan II (d. 1094), king of Scotland (1094), was the eldest son of Malcolm III. He was given as a hostage following Malcolm III's submission to William I at Abernethy in 1072, and remained a captive in England until freed by William II in 1087. William II gave him military backing in a bid to oust his uncle Donald III from the kingship in 1094. He was killed by Mael Petair, mormaer of the Mearns, and his uncle restored to the kingship.
