Gordon Strachan has left his position as Scotland manager by "mutual consent".
The decision, taken in conjunction with the Scottish FA board, follows two failed qualification campaigns.
Strachan and his assistant Mark McGhee have stepped down with immediate effect.
"On behalf of the board I would like to thank Gordon for his excellent service to the national team," said Scottish FA chief executive Stewart Regan.
Strachan was appointed Scotland manager in January 2013.
