John Jackson (22 February 1811 – 5 January 1885) was a British divine and a Church of England bishop for 32 years.

Jackson was appointed Bishop of Lincoln in 1853 and consecrated by John Bird Sumner, Archbishop of Canterbury, on 5 May at St Mary-at-Lambeth.

He welded together the counties of Lincoln and Nottingham, stimulated the educational work of the diocese, and raised the tone of its clergy.

In 1868, Jackson was unexpectedly selected by Benjamin Disraeli, then prime minister, to be Bishop of London where he continued until his retirement in 1885.

Jackson energetically supported the Bishop of London's Fund, encouraged the organisation of lay help, and, after much hesitation, created a diocesan conference.

Jackson's conflict with controversial cleric Stewart Headlam, whom he dismissed from the curacy at St Mathew's, Bethnal Green, in 1878, was widely known.
