John Major Henniker-Major, 5th Baron Henniker VD DL (7 November 1842 – 27 June 1902), was a British peer and Conservative politician.

Henniker was the son of John Henniker-Major, 4th Baron Henniker, and was educated at Eton and Trinity College, Cambridge,

Henniker was elected Member of Parliament for East Suffolk in 1866 (succeeding his father), a seat he held until 1870, when he succeeded his father as fifth Baron Henniker and second Baron Hartismere. The latter title had been granted to his father in 1866 and gave him a seat in the House of Lords (in contrast to the barony of Henniker which was in the Peerage of Ireland). In 1877 Henniker was appointed a Lord-in-Waiting (government whip in the House of Lords) in the Conservative government of Benjamin Disraeli, a post he held until the government fell in 1880, and again under Lord Salisbury between 1885 and 1886, 1886 and 1892 and briefly in 1895. He was appointed Lieutenant Governor of the Isle of Man in 1895, serving as such until his death in 1902.

Lord Henniker was for many years chairman of the quarter of sessions and of the county council for East Suffolk. He was an Honorary Colonel of the 6th Volunteer Battalion of the Suffolk Regiment, and received the Volunteer Officers' Decoration.
