The 26-year-old centre-half has joined Norwich for an undisclosed fee.
Bassong has signed a three-year contract with Norwich.
“Sebastien is a player that I have known well since my time at Newcastle and I’m delighted to have brought in someone with the Premier League experience he has got,” Norwich boss Chris Hughton told the club’s official website.
“He will give us power and pace at the back and again add to the competition in the squad.”
