John Evelyn Denison, 1st Viscount Ossington, PC (27 January 1800 – 7 March 1873) was a British statesman who served as Speaker of the House of Commons from 1857 to 1872.

A Whig, he became Member of Parliament (MP) for Newcastle-under-Lyme in 1823,[1] being returned for Hastings three years later,[2] and holding for a short time a subordinate position in George Canning's ministry.

While in office, Denison formed the view that the public needed a plain, but complete and accurate, explanatory commentary on the Bible, and consulted some of the bishops as to the best way of supplying the work.

Eventually the Archbishop of York undertook to organise the production of the commentary, under the editorship of Frederic Charles Cook, Canon of Exeter.

Lord Ossington married Lady Charlotte, daughter of William Bentinck, 4th Duke of Portland, in 1827, but he left no children.
