Reports had claimed that the British number one would pop the question following the conclusion of the ongoing US Open in New York.
However, the 25-year-old has insisted that there is "no truth" in the rumours.
"I don't think I've been to a jewellery shop for three or four years," he told Sky Sports News. "There is no truth in that yet. Maybe in the future but I have got no plans for that."
Some bookmakers were recently taking bets on when Murray would be getting down on one knee.
