The firm, which sells more than 50 million cups of coffee each year, announced it will serve takeaway hot drinks at its 950 pubs.
Chief executive John Hutson said: "Our coffee is extremely popular with customers. We sell around a million cups a week in our pubs across the UK, and believe customers will welcome the opportunity to enjoy a takeaway cup too, at 99p."
The move follow's the group's decision to maintain staff perks and bonuses despite having to fork out extra cash for the national living wage.
Tim Martin told the Press Association back in April that JD Wetherspoon would keep bonuses and perks for the group's 37,000 staff because it is a "groovy company".
He said: "I'm not going to cut any perks for employees as a result of the national living wage, we're a groovy company.
"About 40% of our profits go to staff in the form of bonuses and free shares, and there are no plans for that to change."
