Wade Elliott has signed a new one-year contract with Birmingham.
The experienced midfielder joins Paul Robinson, Akwasi Asante, Callum Reilly, Mitch Hancox and Colin Doyle in committing his future to the club.
Elliott has become an integral part of the Blues squad since moving to St Andrew's from Burnley during the summer of 2011.
The 34-year-old made 47 appearances and netted nine times last season to add to the six goals he scored from 40 outings in the 2011/12 campaign.
Birmingham boss Lee Clark told the club's official website: "I'm delighted we have got Wade back. He was a really important member of the team last season. He worked very hard for the team and scored some valuable goals.
"He is fantastic example to the younger players and I really wanted him to be part of this season, so it's great to have him back."
