David Erskine, 9th Earl of Buchan, 4th Lord Cardross (3 January 1672 – 14 October 1745) was a Scottish nobleman. He was the son of Henry Erskine, 3rd Lord Cardross, and Catherine Stewart. He was styled Master of Cardross and then Lord Cardross until 1695, when he became the Earl of Buchan.

Buchan was made a Privy Counsellor by King William III in 1697. He served as governor of Blackness Castle from 1702 to 1714 and was Lord Lieutenant of Selkirkshire and Clackmannanshire. He opposed the 1707 Act of Union, which led to him losing some offices. Although related to the Jacobite Earl of Mar, he supported the Hanoverian cause during the Jacobite risings. He joined the Duke of Argyll to help quell the 1715 rising.

After 1715 he sat in the House of Lords as a Scottish representative peer until 1734. In 1697 he married Frances Fairfax, heiress of Henry Fairfax of Hurst, Berkshire, and they had a son, Henry David Erskine, who became the 10th Earl of Buchan. Frances died in 1719, and he later married Isabella Blackett, daughter of Sir William Blackett, 1st Baronet; they had no children.
