Blanchardstown Centre was evacuated by Gardai as part of a security operation earlier this evening.
The operation, which began shortly after 5pm, has now been stood down after officers completed searches of the area.
A number of armed Gardai were among the units at the scene.
The centre is due to open as normal tomorrow.
Gardai say they will not be commenting further on the operation.
Local Sinn Fein Councillor Paul Donnelly said there was huge congestion around the approach roads to the centre during the operation, with roads on 'complete lockdown'.
