Martin O'Neill has stepped down as the manager of the Republic of Ireland, following Monday's 0-0 draw with Denmark.
Assistant manager Roy Keane and coaches Seamus McDonagh Steve Guppy have also left their roles.
O'Neill took over in November 2013, and was in charge for 55 matches, winning 19, drawing 20 and losing 16, giving him a win ration of 35%.
The Football Association of Ireland president Donal Conway said: "On behalf of the FAI Board, I would like to thank Martin, Roy, and the management team for their work with the Republic of Ireland team over the last five years."
O'Neill, who replaced Giovanni Trapattoni, guided Ireland to the Euro 2016 finals and oversaw famous victories over Germany and Italy during his time in charge.
FAI chief executive John Delaney said: "I would like to thank Martin, Roy, and the management team for the impact that they had with the Ireland team.
"There have been many highlights during Martin's reign - none more so than Euro 2016 in France, which will live long in the memory of all Irish supporters.
"Martin did a great job guiding the team out of a difficult qualifying group - where we beat World Champions Germany along the way - to reach Euro 2016 and advance to the last 16 following a historic victory over Italy in Lille.
"I wish Martin, and the management team, the very best for the future."
