West Attica (Greek: Περιφερειακή ενότητα Δυτικής Αττικής) is one of the regional units of Greece. It is part of the region of Attica. The capital of the regional unit is the town of Eleusis. The regional unit covers the western part of the agglomeration of Athens, and the area to its west.

With respect to parliamentary elections West Attica belongs to the electoral district of Attica.

As a part of the 2011 Kallikratis government reform, the regional unit West Attica was created out of the former prefecture West Attica (Greek: νομαρχία Δυτικής Αττικής). The prefecture had the same territory as the present regional unit. At the same time, the municipalities were reorganised, according to the table below.

There were two provinces in the prefecture of West Attica: Megarida, and the Attica Province (most of which was part of East Attica). They were abolished in 2006.
