Northern Ireland captain Steven Davis has signed a new deal at Southampton that runs until the summer of 2019.
The 31-year-old, who has 81 caps, joined Saints in 2012 from Rangers.
He has made 155 appearances for the Premier League club and scored 11 goals, including five last season.
Saints executive director of football Les Reed said: "I am delighted that Steven, another influential leader in the dressing room and on the pitch, has committed his future to Southampton."
Goalkeeper Fraser Forster, midfielder James Ward-Prowse and defender Virgil van Dijk have also signed new deals in the past six weeks.
