The Man in Seat Sixty-One is a British travel website created, written and maintained by Mark Smith, a former rail industry worker.

[4] Smith subsequently wrote a book based on the site titled The Man in Seat 61: A Guide To Taking The Train Through Europe.

Published by Bantam Press in 2008, the book mirrored the website in offering an "essential guide for anyone who wishes to travel to Europe and beyond by train".

This was followed by a second book in 2011, The Man in Seat 61: Worldwide, covering international train travel around Africa, Asia, the Americas and Australasia.

A pilot episode featuring actor Kenneth Cranham was released covering the journey from London to St Petersburg by rail as far as Waterloo, Belgium.
