The 36-year-old England and British & Irish Lions front-rower has made 140 appearances for Tiger since his debut in 2003 and is recognised among the top props in world rugby.
Tigers head coach Richard Cockerill said: “Everyone knows what Julian brings to the game. He is in the very top category of scrummagers in world rugby and experience counts for a lot in the front row.
“He has been a great servant of Tigers over the last six years and is a popular guy with his colleagues and the supporters. I’m delighted that he has agreed terms to continue playing for us.
“Julian combines his rugby with his farming commitments and I’m sure he’d say that balance helps to keep him fresh and enthusiastic about the game.”
White, capped 51 times by England since his debut in 2000 and in three Tests with the Lions, made his Tigers debut in November 2003 after his return from England’s Rugby World Cup win in Australia.
He passed 100 starts for the club in 2008/09 and has won two Guinness Premiership titles, an EDF Energy Cup and played in two Heineken Cup Finals in his time with the club.
White said: “I’m still enjoying my rugby and my time at Leicester Tigers, so I was very pleased to agree a new contract at the club. This is a great place to play your rugby and any player wants that to continue as long as possible.”
