Ian Madigan has extended his contact with Leinster until the end of the 2015/16 season.
The 24-year-old out-half featured 32 times for the province last year in a campaign that also saw him earn the first of his four Ireland caps.
Madigan made his debut against the Dragons in May 2009 and has made 81 appearances to date for Leinster, scoring 337 points.
Commenting on the news Leinster coach Matt O'Connor said: "We are delighted that Ian has extended his stay with Leinster.
"He displayed a real level of consistency in his performances last year, which was recognised by his peers in being voted the Bank of Ireland Players’ Player of the Year as well as picking up the Golden Boot award as the top kicker in the PRO12."
