Marquess of Queensberry is a title in the peerage of Scotland. The title has been held since its creation in 1682 by a member of the Douglas family. The Marquesses also held the title of Duke of Queensberry from 1684 to 1810, when it was inherited by the Duke of Buccleuch.

The subsidiary titles of Lord Queensberry are: Earl of Queensberry (created 1633), Viscount of Drumlanrig (1628) and Lord Douglas of Hawick and Tibbers (1628), all in the peerage of Scotland. He is also a Scottish Baronet, styled "of Kelhead", created 26 February 1668, so the 6th Marquess was the 5th Baronet. The courtesy title used by Lord Queensberry's eldest son and heir is Viscount Drumlanrig. There is no special courtesy title for Lord Drumlanrig's eldest son and heir, so assumably he would be styled as Honourable as presumably would be all sons of Lord Drumlanrig.

The 9th Marquess is particularly well-known because of the rules of boxing which were named for him (the Marquess of Queensberry rules), and for his litigious interaction with Oscar Wilde.

There was or still is a feudal title Baron Drumlanrig created for an ancestor of the 1st Earl of Queensberry before 1427 when the 1st Baron died. The 1st Earl of Queensberry was the 9th Baron Drumlanrig.
