The 34-year old began his career with the Orchard County 12 years ago and was Benny Tierney's understudy during the All-Ireland winning 2002 campaign.
It is the second notable retirement from the Armagh panel in a week after Steven McDonnell also made the announcement.
Hearty won his sixth All-Ireland club medal recently and will continue to play at club level with Crossmaglen Rangers.
He posted his decision on Thursday night on Twitter.
Hearty said: "After 12 great years I have decided to retire from intercounty football with Armagh. It's a hard decision but I feel the correct one. I would like to thank all current and former players who I have had the honour of playing with.
"Also to my family and friends who have backed me from the start, whatever had to be done. Thank you."
He was an ever present figure in the Armagh goals over the last 10 years.
His departure follows Stevie McDonnell's recent announcement that he is to retire from the county set-up.
