The England lock, 28, has made 142 appearances in 10 seasons at the club.

Launchbury has 62 international caps and was part of the England squad that reached the World Cup final in Japan earlier this month.

"There have been some special moments during the past 10 years and I want to create more of those over the coming seasons," he told the club website.

"Hopefully as a club we keep developing and growing more and more Premiership-class players, and compete for silverware moving forward."

Launchbury made his top-flight debut for Wasps in 2011 as a teenager, skippering them to the Premiership final in 2016-17.

In England colours he featured at the 2015 World Cup and was a part of the 2016 Six Nations Grand Slam-winning squad.

"He is a born leader, who adds a lot to this team and having someone of his ilk pledging their future to the club is a real statement of intent," said Wasps director of rugby Dai Young.

Launchbury limped off with a calf strain in Wasps' Challenge Cup win over Agen on Saturday - his first game since facing the USA with England in the World Cup pool stages.

Meanwhile, centre Ross Neal will be leaving the club in December to join Seattle Seawolves in Major League Rugby in the United States.

The 23-year-old made 13 first-team appearances having first arrived in the summer of 2018.
