King’s previous deal was set to expire at the end of June, but the new deal will keep him at the club until the summer of 2012.
“I am delighted to have signed a new contract with Spurs,” he told the club’s official website.
“I have been here since I was a schoolboy and I could never see myself going anywhere else. This is where I want to continue playing my football.
“We’ve got the prospect of Champions League football to look forward to next season and with the quality of players we have I believe we are on the brink of something big.
“It is an exciting time for the club with a new training ground being built and plans for a new stadium.
“I am enjoying my football and I want to be a part of what is happening here.”
