The Ivory Coast full-back, who has already played 104 times for the Swabians, will continue to compete with Cristian Molinaro for a place on the left-hand side of Bruno Labbadia's defence next season. His stay will be automatically extended by a further year if he makes enough appearances for the club next season
"We are delighted that Arthur has accepted our offer of a contract and showed his continued commitment to VfB," Stuttgart director of sport Fredi Bobic said on the Bundsliga club's website.
"Arthur is an international player who will do our team good with is quality and also his personality."
The 29-year-old defender added: "I have always stressed that I feel very happy at VfB and I am therefore very happy to be able to extend my contract here."
Boka joined Stuttgart from Strasbourg in 2006 and is now one of the club's longest-serving players and one of the few remaining members of their 2007 Bundesliga-winning squad.
