The winger, 26, has been one of Saints' most impressive performers in the Premier League this season but only had a matter of months remaining on his current deal.
Newcastle were among those linked with a summer move for Puncheon, who ended such talk by signing a new deal at St Mary's.
"It feels amazing," Puncheon told the club's official website. "It's obviously been a worry because my contract was up at the end of the season, so it was important for me to get tied down.
"It's a weight off my mind, so now I can look to the long-term future. The club has a vision, and that's why I've signed and stayed on.
"We got to the Premier League in three years, and now the club has a vision of playing European football - and we want to get there as soon as possible.
"I believe that can happen and, more importantly, the football club believes that can happen. They believe I can be a part of it and so do I.
"Now I want to finish the season strongly and keep growing as a player - and for us to keep growing as a football club."
Saints manager Mauricio Pochettino added: "It's great news that Jason has agreed to sign a new contract with Southampton. He has been very impressive for the club this season and especially so since I arrived, and he is a very important member of our squad.
"He has responded really well to the challenge of the Premier League and is clearly playing some of the best football of his career, so it's really pleasing that he is staying here.
"Jason is a determined and passionate person, and that honesty and emotion has transferred into his performances and so he fully deserves this contract extension.
"I was never in any doubt that he would like to remain at Southampton, and I am looking forward to seeing even more from Jason over the next few years."
