Bremer River is a river in Western Australia that rises near Jerramungup at the border of the Yilgarn plateau.

The river flows in a generally south-easterly direction and the river valley becomes steadily deeper as the river approaches the coast, where it has eroded the Pallinup siltstone deposits that deposited over the underlying granite.

About 80% of the catchment area has been cleared for agriculture, mostly for cropping and grazing.

[4] The river is saline varying from 3-4‰ to 150‰ depending on the season.
