Former England captain Chris Robshaw has signed a new contract with Harlequins that will keep him at the club until 2020.
The three-year extension will take the 31-year-old into his 15th season as a first-team member at Twickenham Stoop, where he made his debut in 2005.
Robshaw said: "I am extremely proud to have re-signed with the club who gave me my first chance as a player and I've cheered for since I was a child.
"I thank Harlequins and the supporters for the incredible continued support that's been shown to me. John Kingston and the coaching team have recruited well and we have our sights firmly set on getting silverware this year.
"I look forward to seeing all the supporters at The Stoop in September for what's sure to be an exciting season."
Since making his debut against Doncaster in October, 2005, academy graduate Robshaw has gone on to make 239 appearances for Harlequins.
Robshaw captained his boyhood club to Challenge Cup success in 2011 and the Aviva Premiership title 12 months later, while being handed the armband for England under Stuart Lancaster.
He led his country during their disappointing 2015 Rugby World Cup campaign but has recovered admirably from that setback to become a key member of Eddie Jones' squad.
"His influence within the group is immense and I know, in talking at length with him, he has an incredible appetite to win further major domestic and European honours," Quins director of rugby John Kingston said.
"This is brilliant news for Harlequins at a time when we are preparing for what will be an incredibly exciting season, back in the Champions Cup."
