"The Lord Neville of Pounceney" is a self-styled title used by the patron of a modern, non-mainstream fraternal or chivalric organization calling itself the "Autonomous Sovereign Military Order of the Temple of Jerusalem".

The title is associated with the following details:

• Affiliation: He serves as the patron listed on official application materials for this specific modern Knights Templar revival group.

• Post-Nominals: His title is accompanied by a long string of post-nominal acronyms, including K.G.C.T. (Knight Grand Cross of the Temple), OM (Order of Merit), FRSA (Fellow of the Royal Society of Arts), LRPS (Licentiate of the Royal Photographic Society), ABIPP (Associate of the British Institute of Professional Photography), and AMPA (Associate of the Master Photographers Association).

• Historical Context: Despite the use of the historic aristocratic surname "Neville", "Lord Neville of Pounceney" is not a recognized historical peerage in the United Kingdom or medieval England. Instead, it is an invented or self-assumed title used within the context of private neo-chivalric societies
