"Per-Mathias and the NFF have agreed that Høgmo will end his functions as Norwegian manager," the NFF said in a statement.
Norway have lost to Germany (3-0), Azerbaijan (1-0) and last Friday 2-1 to Czech Republic and are second bottom in Group C. They have one win over San Marino.
"I still have great faith in the team and the players who are there. After the last match I thought that it was important to [...] think things through. And eventually I decide that the pressures on the players and the team, not to mention the organization, had become so great that the right thing to do is retire. Otherwise it would feel like I was putting myself over the team," Høgmo said at a press conference.
The 56-year-old Høgmo coached 35 games for the national team, ending with a record of ten wins, 18 losses and seven draws.
