Sir David Erskine (1772 – 22 October 1837) was a Scottish dramatist and antiquary.
In early life, he bore a captain's commission in the 31st foot, and also belonged to the York Rangers.
On the reduction of the 31st regiment, he was appointed a professor at the Royal Military College, Sandhurst.
The Earl of Munster was there placed under his tuition, as were others of William IV's children, and at their request, Erskine received the honour of knighthood on 11 September 1830.
His father died in 1829 and bequeathed to him for life the whole of his unentailed estates, including Dryburgh Abbey, Berwickshire, which thenceforth became his permanent residence.
