The 27-year-old has impressed since making his move to the Britannia four years ago and has duly been awarded with a new deal which will keep him at the club until 2015
The Republic of Ireland international has been a big hit at the Britannia since making his 2008 move from Sheffield Wednesday.
Stoke manager Tony Pulis revealed his delight to have tied the midfielder to a new long-term contract, insisting Whelan has been an integral part to the club's recent success.
"Glenn has played a big part in our achievements since he came to the Club and it is important to look after players who have been the bedrock of that success," Pulis told the club’s official website.
"He has had a fantastic time these past 12 months, and he's shown that he's a player who thrives on being challenged to step up to the next level.
"That's probably the Celtic blood in him and a steely determination to prove people wrong, which has included even myself on occasions."
Whelan’s spell at Stoke has seen him help the side to promotion into the Premier League, an FA Cup final last season and Europa League qualification, while he has also won his first international cap.
Whelan commented: "I am loving life at the moment and things are going really well, so I am absolutely delighted to commit my long term future to the Club.
"We have enjoyed a remarkable past few years with everything that we have achieved and I believe that even more success can be achieved in the future.
"I am very excited about what the next few years could have in store, and I am proud to be a part of it as we look to continue the Club's excellent progress.
"All of the hard work I have done over the past 12 months has paid off. To play at Wembley twice, reach the FA Cup Final, play in Europe and be doing well at international level has certainly made it a memorable time for me."
