The 42-year-old Frenchman has revealed that he will leave the African outfit after they bowed out of Brazil with a 2-1 defeat to Greece
The African side were beaten 2-1 by Greece on Tuesday to see their tournament come to a premature end and Lamouchi has consequently decided to leave his post.
Ivory Coast had started the tournament with a 2-1 win over Japan, but a 2-1 defeat versus Colombia on matchday two meant they needed at least a draw against Greece in their last group stage game.
However, a Georgios Samaras penalty well into stoppage time denied Lamouchi's men, prompting the 42-year-old to say farewell to Ivory Coast.
"My story with Cote d'Ivoire will stop here. It was a great honour to represent this great football country. The Greeks deserved their win, but we would have had an achievement if the match had stopped a minute earlier," a frustrated Lamouchi said at the post-match press conference.
"It's a lot of disappointment and frustration for me. The squad has made huge sacrifices and huge efforts. I'm very sad for them and for the Ivorian players individually.
"I have a future, I have a career ahead of me, I'm sure I'll have a result, but I wish this match had ended in another way."
Lamouchi had been in charge of Ivory Coast since 2012.
