Goalkeeper Danny Rogers and defender Scott McKenna have signed new deals that will keep them at the Pittodrie club until the summer of 2018.
Rogers, a Republic of Ireland Under 21 internationalist, is on loan at Falkirk and has been a key player for Peter Houston's men this season.
McKenna made his first-team debut for the Dons earlier this year and has had previous loan spells at Ayr United and Alloa Athletic.
Dons boss Derek McInnes told the club website: “It is great news that both lads have committed their futures to Aberdeen. The challenge for both Danny and Scott now is to establish themselves in the first team. We feel that both have the chance to do so."
