William Bentinck, 2nd Duke of Portland KG (1 March 1709 – 1 May 1762), styled Viscount Woodstock from 1709 to 1715 and Marquess of Titchfield from 1715 to 1726, was a British peer.
Portland was the son of Henry Bentinck, 1st Duke of Portland and his wife Elizabeth Noel, daughter of Wriothesley Baptist Noel, 2nd Earl of Gainsborough. He succeeded his father in the dukedom as a teen in 1726. He was an original governor of the Foundling Hospital in London, founded in 1739, and was made a Knight of the Garter in 1741. He married Lady Margaret Harley, daughter of Edward Harley, 2nd Earl of Oxford and Earl Mortimer. They had six children:
Lady Elizabeth Bentinck (Welbeck Abbey, 27 June 1735 – 25 December 1825, London), who married Thomas Thynne, 1st Marquess of Bath (1734-1796)
Lady Henrietta Bentinck (8 February 1737 – 4 June 1827), who married George Grey, 5th Earl of Stamford (1737-1819)
William Henry Cavendish-Bentinck, 3rd Duke of Portland (b. 14 April 1738; d. 30 October 1809), who married Lady Dorothy Cavendish (1750-1794) daughter of William Cavendish, 4th Duke of Devonshire
Lady Margaret Bentinck (26 July 1739 – 28 April 1756)
Lady Frances Bentinck (9 April 1741 – March 1743)

Portland is identified in The Handy-Book of Literary Curiosities (1909) as one of the perpetrators of The Great Bottle Hoax of 1749, in which a large crowd was lured to a London theatre with the expectation of seeing a man jump into a "quart bottle".
