The 36-year-old right hander, in a letter to the SLC, has informed his decision and was scheduled to meet the national selectors later this evening.
Sources close to the batsman said he was disheartened by the treatment meted out to him when he was originally axed from the 20-member squad chosen for the upcoming home Test series against Bangladesh.
He was later included in the squad to replace former captain Mahela Jayawardene, who was going to miss the series through injury.
A veteran of 81 Tests, Samaraweera has amassed 5462 runs at an average of 48.76 and it includes 14 centuries.
Samaraweera, who is considered a highly dependable middle order batsman, is all set to play for Worcestershire in this summer's English county championship.
