Belton, who captained her country 26 times, made her international debut against France at the European Championships in 2000.
In 2003 she was part of the Irish team which beat Spain for a first ever win for Ireland in the Six Nations and since then she has been part of sides who have overcome Italy, Wales and Scotland in the same competition.
At the IRB Women's Rugby World Cup in 2006 she was the only Irish player named in the tournament's All-Star team, taking the number 10 spot.
In her career she has also played for Limerick clubs Shannon and UL Bohemians and for provincial side Munster.
She will be remembered as one of Ireland's best ever attacking players with her eye for the try-line complemented by some top drawer kicking and defensive skills.
Current Ireland team manager Rachel Reid, who was also Belton's team-mate during her early international career, said: "Sarahjane has an impeccable Irish team record.
"She started 60 consecutive Test matches for Ireland and has been ever present since the start of what I regard as the 'new era', which started at the European Championships in Spain 2000.
"Back then she was referred to as a 'promising young full-back', however she developed into a world class player and inspirational leader, both on and off the pitch.
"She has been instrumental in building the camaraderie and team spirit within the team since she first broke into the squad."
Reid added: "It has been a pleasure sharing her international years with her, both on and off the pitch, and I look forward to sharing many more years of rugby with her, albeit from the sidelines."
