Regan King, 33, has signed a new two-year deal with the region he calls his 'spiritual rugby home'.
Scarlets Head Coach Simon Easterby said: "To have the quality and experience of a player like Regan King back in our squad next season will be a big positive for our region as a whole.
"Not only will we have secured a rugby player of real quality on the pitch who has played at the top end of European and French rugby for the past two years, but we've also gained the value of a professional who has such rounded experience which can be passed onto others.
"He's shown his inherent quality as a player in his recent performances in the Heineken Cup as well as the domestic French game and is a player any club in Europe would want in their ranks."
New Zealand-born King achieved his All Blacks cap against Wales at the Millennium Stadium in November 2002. He also played for Paris based club Stade Francais before leaving to join the Scarlets in the 2005/6 season.
He has appeared 143 times in a Scarlets shirt with 180 points.

"It's vital that you win your home games in the Heineken Cup and if you can get points on the road then that's a big advantage."
"But this won't mean anything we don't get a result at home nest weekend. This was a big performance but we have to keep our feet on the ground."
