Henry William Massingham (25 May 1860 – 27 August 1924) was an English journalist, editor of The Nation from 1907 to 1923.

[6] He edited the Daily Chronicle 1897–1899, but in November 1899 was forced out because his editorial line on the Second Boer War was hostile to the government.

A change of ownership was putting control in the hands of John Maynard Keynes, a Liberal.

In July 1914, with the threat of war and refusal of the government to deny the possibility of British involvement, Massingham and H. N. Brailsford voiced their opposition to intervention in The Nation as did other Liberals in the Manchester Guardian, The Economist, and Daily News.

[8] Massingham during the short remainder of his life was a columnist, in the Christian Science Monitor and The Spectator.
