The twins join Willie Cauley-Stein, Marcus Lee, Alex Poythress and Dakari Johnson, all of whom bypassed the NBA Draft to return for the 2014-15 campaign.
"I'm excited about Aaron and Andrew's decision to return for next season," Kentucky head coach John Calipari said. "Their postseason play was a result of the improvement they made all season and displayed what they're capable of doing on the court. I look forward to having the opportunity to work with them during the summer and watch them lead next year's team."
Aaron Harrison started all 40 games for the Wildcats this past season and averaged 13.7 points and 3.0 rebounds per game. He made his mark in the NCAA Tournament by knocking down three of the school's all-time most memorable shots in three consecutive games in helping Kentucky past Louisville, Michigan and Wisconsin. The Wildcats lost to Connecticut in the national championship game.
"I'm coming back for a second season in large part because last year's title run was special, but we still have unfinished business," Aaron Harrison said.
Andrew Harrison started 39 games and averaged 10.9 points and 4.0 assists per game.
"I'm returning for my sophomore season because I want to win a national title." Andrew Harrison said.
The Wildcats did lose Julius Randle and James Young as early-entry candidates for the NBA Draft.
