Ferrari will have an unchanged line-up next season after team principal Marco Mattiacci confirmed the pair for the 2015 campaign.
Sky Sports F1 reports that Mattiacci 'has insisted to Martin Brundle that both drivers will remain with the team for next year'.
The pay channel is set to broadcast a full interview on Sunday.
Alonso's contract with Ferrari runs until the end of the 2016 season while Raikkonen has another year left, but there were speculation over the future of both in recent months.
With Ferrari once again struggling to challenge not only for the Drivers' Championship, but also for race victories, two-time World Champion Alonso was linked with a move back to McLaren.
There have also been suggestions that Ferrari could get rid of Raikkonen at the end of this campaign as the Finn has had a poor season by his high standards. While Alonso has appeared twice on the podium, Raikkonen's best finish is a P6 in Hungary last time out.
