Scotland will host Estonia at Aberdeen's Pittodrie ground next year in preparation for the second half of their 2014 World Cup qualifying campaign.
Craig Levein's side face the Eastern Europeans, who were beaten in the Euro 2012 play-offs by Republic of Ireland in November, on 6th February.
Scotland begin their bid to reach a first World Cup since 1998 next month and will play Estonia ahead of the crucial Group A double-header against Wales and Serbia in March.
Levein said: "It is important that we continue to take the national team throughout the country and I am sure our huge support in the north east of Scotland will turn up in numbers.
"Like our recent victory against Australia, the Estonians will provide a tough and relevant challenge at the midway point of our World Cup qualifying campaign.
"The Estonians have improved markedly in the last two years. They reached the play-offs for Euro 2012 against Republic of Ireland, and they will provide a good test."
