Milovan Rajevac has resigned as coach of Algeria after only two matches in charge of the Desert Foxes.
His decision follows a 1-1 draw at home to Cameroon on Sunday in Group B of 2018 World Cup qualifying.
The 62-year-old Serb met with the Algeria Football Federation president Mohamed Raouraoua on Tuesday to discuss the result, and his departure was announced shortly afterwards.
Rajevac replaced Frenchman Christian Gourcuff, who left the job in April.
Algeria's next 2018 World Cup qualifier is away to Nigeria on 12 November.
Only the group winners will qualify for the tournament in Russia.
