William Kennedy Jones (4 May 1865 – 20 October 1921) was a British journalist, editor, businessman, newspaper manager and Member of Parliament.

Though his contribution to starting a new newspaper, The Evening, in 1892 proved futile, he remained convinced that a halfpenny morning daily would be economically viable.

Though enjoying a circulation of 100,000, the newspaper was running at a loss, and Jones and Tracy both hoped to sell the paper quickly to Alfred Harmsworth, who was looking to purchase his first London daily.

Though not the editor, Jones was in charge of the style and content, and his instinct for what his readers wanted helped make the Daily Mail a runaway success, growing from an initial planned run of 100,000 to over 500,000 copies in circulation within three years of its launch.

He ran as an independent in a 1916 by-election for Wimbledon, enjoying a protest vote against the prevailing wartime party truce but ultimately losing the seat to Stuart Coats.
