Jack Carty has signed a two-year contract extension with Connacht until the end of the 2020/21 season.
The Roscommon man made his Connacht debut as an academy player in September 2012 and has gone on to make 118 appearances for his home province.
At international level he has represented Ireland at Under-20 level.
The out-half has been in excellent form so far this season and in his 12 appearances in the Pro14, he has scored 109 points, the second highest in the competition.
Carty said: "I am hugely proud that as a Connacht man I have come through the grassroots structures in the province and gone on to play professional rugby.
"I have a great support network in rugby and away from the game and I am very grateful for the guidance they show me.
"Connacht is an exciting place to be at the moment both on and off the field and we are extremely ambitious about what we can achieve in the coming seasons. I look forward to contributing to those plans".
Connacht head coach Andy Friend said Carty is a shining of example of their academy work:
"He is an example of what our Grassroots to Green Shirts Vision represents," he said.
"He will continue to be an important player for the province in the seasons ahead."
