John Leland (18 October 1691 – 1766) was an English Presbyterian minister and author of theological works.

He was ordained co-pastor to Nathanael Weld (1660–1730) at New Row Presbyterian Church, Dublin, on 16 December 1716.

[3] He is remembered as the author of A view of the principal deistical writers that have appeared in England in the last and present century: with observations upon them, and some account of the answers that have been published against them: in several letters to a friend.

Six chapters are about David Hume's views on religion, and approximately half of the work deals with Bolingbroke.

[4] The Eustace Street Meeting House where he ministered for 50 years, was a Presbyterian/Unitarian Congtregation, eventually merging with other Unitarian groups in Dublin.
