Robert Duncanson, 1658 to May 1705, was a Scottish professional soldier from Inveraray; a retainer of the Earl of Argyll, he began his career during the 1685 Argyll's Rising, and is now best remembered for his involvement in the February 1692 Glencoe massacre.

Following the failure of the 1685 Rising, he escaped to the Dutch Republic, and returned after the 1688 Glorious Revolution in Scotland. During the Jacobite rising of 1689, he commanded the Earl of Argyll's Regiment of Foot, the primary unit involved in the Massacre, after which he was posted to Flanders for the Nine Years' War, where he remained until the 1697 Treaty of Ryswick.

When the War of the Spanish Succession began in 1701, he served in Flanders until 1704, when he was posted to Spain and Portugal; in May 1705, he died of wounds sustained leading an assault on the Spanish border town of Valencia de Alcantara.
