The 33-year-old missed out on a place in the France squad for the World Cup this summer due to an achilles injury suffered in Arsenal's Europa League semi-final clash with Atletico Madrid.
That saw him miss out on a winner's medal as France emerged victorious in Russia, with Koscielny now opting to call time on his career having made 51 appearances since making his debut in November 2011.
"I think that I have given everything I can for France, I am 33, I have done two Euros, one World Cup," Koscielny told French TV station 'Canal+'.
"France has a great generation of great players now. My injury does not change my decision. For Les Bleus, it is finished.
"When you are in good form, you have lots of friends. When you are injured... after a certain period of time, you are forgotten about.
"He [Deschamps] called me once for my birthday in September. Otherwise, no. Lots of people disappointed me. Not only the coach. It feels like a hit on the back of the head.
"France's World Cup victory did me a lot more psychological damage than my injury did me."
Koscielny's last appearance for his country came in a 3-1 friendly victory over Russia in March.
