The three-year extension will keep the 26-year-old at Stoke until the summer of 2014.
“This has capped an amazing few days for me,” said Wilkinson. “Being a local lad, it’s always been a dream of mine to play for this club, never mind having the chance now to play in an FA Cup Final following our win at the weekend.
“It’s been remarkable to see the progress this lub has made in my time here and I am excited about what the future holds in store for us.”
“This could go down as one of the most successful seasons in the club’s long history and at a time like this it is important that we look after those players who have helped get us where we are today,” Stoke boss Tony Pulis told the club’s official website.
“Andy is certainly one such player deserving of that recognition and I am sure that he has an equally vital role to play in our future.”
