Greig Laidlaw has signed a new two-year contract to keep him at Edinburgh until the summer of 2014.
Laidlaw, who was recently made captain, is in his sixth season with the Scottish capital side.
"I'm really happy to be staying at Edinburgh Rugby for another two years," he said.
Coach Michael Bradley added: "The quality of Greig as a rugby player and a leader has already shown through this season."
Scrum-half Laidlaw has previously captained Scotland A and featured for the senior side. Though he made Andy Robinson's provisional World Cup squad, he missed out on final selection.
"One of the big pros for me as an individual is that I believe I can best push my case and promote my aspirations for Scotland selection by playing at Edinburgh Rugby," said the 25-year-old.
"Being named as captain also played a big part in re-signing as it's important to me and my own ambitions to be a leader. I'm a young captain so I think it will be good for me in the years to come.
"There's a lot of good feeling and exciting changes happening off the pitch while we're about to start a new chapter under head coach Michael Bradley.
"There are a lot of good young players coming though the club and I think that if we can build on their ability we can progress as a club, improve our league position and build our crowd and support."
Bradley has been impressed by Laidlaw's attitude, adding: "He leads by example and sets very high standards for himself and others; that is the critical element.
"He's an extremely hard working individual and has reacted very positively to what we are trying to do at the club and the part he can play, through his leadership and performance, in helping this club grow and prosper."
