Abrera (Catalan pronunciation: [əˈβɾeɾə]) is a municipality in the comarca of the Baix Llobregat in Catalonia, Spain.

It is situated in the valley of the Llobregat river, to the south-east of Montserrat, on the main A2 road between Barcelona and Lleida.

The municipality is served by the FGC railway line from Martorell to Manresa: the S4 and R5 services stop at the station.

The remains of protohistoric ceramics found in the Barcelones estate and the vestiges of a field of silos from the Iberian era in the Torrent Gran, constitute the first indications of the existence of habitat in the municipality.

[5] From the 15th-16th century onwards, the town grew with buildings and population, even during times of epidemics.
