Everton announced on Thursday that England international centre-back Phil Jagielka has extended his contract at the club by two years to 2017.
The 30-year-old joined Everton from Sheffield United in 2007 and has since made close to 200 appearances in all competitions.
He was a member of the England squad at Euro 2012 and has made 16 international appearances.
"We are delighted Phil has agreed to commit his long-term future here at Goodison Park," chief executive Robert Elstone told the club website.
"Phil is a hugely important and influential player and I, like many Evertonians, look forward to seeing him play in a blue shirt for many years to come.
"Discussions have been taking place for a short while and, now they are completed, I would like to thank Phil and his representatives for the professionalism and courtesy shown throughout those negotiations."
