The Republic of Ireland international has put pen to paper on a new deal that will see him remain at Villa Park until 2016
The 23-year-old defender, who has progressed through the ranks at the club, revealed his pride at securing the new deal, which will see him remain at Villa Park until the 2016 season.
"From a personal point of view, I really couldn't be more delighted or more proud," he told the club's official website. "I've been here since I was 12 years old, progressing from the younger teams through the youth team along with players such as Marc Albrighton, Barry Bannan and another couple who have just signed new deals in Nathan Baker and Andi Weimann.
"It's great that we've all managed to come through together and there's a bond there with this club that's as close as family to us lads especially."
After securing a new contract, the centre back is now looking ahead to the new season and says that he "can't wait to start."
He said: "This season will be another tough challenge but we have the players and we have a good young squad, everyone is hungry for it, we're working as hard as we can and we can't wait to start."
A current Republic of Ireland international, Clark has captained Villa at all levels and has made 75 appearances in all competitions for the club, scoring six times.
