Lustenberger, who has made 219 competitive appearances for Hertha, has put pen to paper on a deal that will extend his stay at the Olympiastadion.
"Hertha have given me an enormous amount, and I'm very grateful for that," said the Switzerland international, who moved to the Old Lady from FC Luzern in 2007. "Berlin has become my second home, and my family and I feel really good here."
The 27-year-old has featured 24 times in the Bundesliga this season, helping Hertha hold on to third place, synonymous with a berth in next season's UEFA Champions League.
"We're in a great position and we'll give everything to further develop the team and achieve maximum sporting success," Lustenberger added on his club's official website.
"'Lusti' is not only an important part of the side because he's the captain," Hertha's sporting director Michael Preetz said. "We noticed very quickly on in the talks that both sides wanted to go into the future together."
