For Murray's show at Glasgow's SEC Armadillo on June 18, tickets are being offered for between £284 and £475.
This represents up to 18 times the original face value of the tickets.
Touts are looking to make quick profits from fans desperate to see the tennis legend share stories from his career.
The Centre Stage tour will visit four UK venues in June, beginning in Glasgow on June 18.
Murray will then move to Edinburgh the following night.
Two London dates complete the tour, with shows at the Eventim Apollo on June 21 and the New Wimbledon Theatre on June 29.
During these events, the former world number one will discuss "pretty much anything" about his career.
The format promises to reveal stories that have never been shared publicly before.
ATG Tickets issued a clear warning to fans, telling The Scottish Sun: "Tickets can't be sold for profit."
The promoters added: "Please don't purchase from a secondary website."
Despite high demand, with many fans calling for additional dates to be added to the tour, organisers are firm in their stance against secondary ticket sales.
The warning aims to protect fans from paying inflated prices for tickets that may not even be valid for entry.
