Wales veteran Halfpenny retires from Test rugby with 'heavy heart'
The 34-year-old, who made his international debut against South Africa in 2008 when he was just 19, will make one further appearance in the red jersey, against the Barbarians on November 4th.
The former Scarlets back won the last of his 101 caps against Portugal last month in the Rugby World Cup before Wales were knocked out of the tournament in the quarter-finals.
He also toured three times with the British & Irish Lions, playing in four Tests.
"After having time to reflect after the Rugby World Cup campaign, it's with a heavy heart that I've decided that it's time for me to step away from international rugby," Halfpenny posted on social media.
"The decision hasn't been easy, but the time feels right for me now and I look forward to running out one last time against the Barbarians next week at home," he added.
Halfpenny left Welsh region Scarlets at the end of last season and has yet to announce where he will continue to play club rugby.
