The 31-year-old has just forced his way back into the Hammers first team after suffering a string of injuries in the last couple of seasons and it in order to prolong his club career the 43 times capped full-back has called it a day.
In a statement released on Monday Gabbidon said, “After nine fantastic years of playing international football for Wales during which I had the honour and privilege of captaining my country, and after long consideration, I have decided to retire from international duty.
“On a personal note, I would like to thank the Football Association of Wales for their support over the years and I would like to thank people of Wales who supported me and my fellow team-mates at every game, home and away, giving their all to the cause - true supporters!
“I would also like to say a special thank you to my family, friends and management team, who have stood by me throughout the many good times and very few bad times.
“It has been a wonderful journey.
“Thank you all.”
