England full-back Mike Brown has committed his future to Harlequins by signing a new long-term contract with the Aviva Premiership outfit.
Brown, 30, has made 248 appearances for Quins after joining their academy in 2002.
"Mike is the epitome of what Harlequins stands for; he has come through our academy and become one of the great full-backs of world rugby," Harlequins director of rugby Conor O'Shea told the club website.
"I have watched him grow and become the bedrock for whatever team he plays for. He maintains the highest of standards off the pitch and will play at the highest level for many years as a result of that.
"We are all delighted he wants to commit to his only club for what will be, in all likelihood, the remainder of his career."
Quins are chasing their first Premiership title since 2012 this year and have won three of their first four matches to lie third in the table.
