Arrowe Brook is a tributary of The Birket, in Wirral, Merseyside. The river starts as lowland field drainage around Irby, Thingwall and Landican. The brook flows through Arrowe Park, Upton Meadow and Greasby, before Greasby Brook converges between Greasby and Saughall Massie. Arrowe Brook then goes beneath Saughall Massie bridge. This was the first bridge constructed by the notable Victorian civil engineer Sir Thomas Brassey, in 1829. The bridge was awarded Grade II listed status by English Heritage, in 2007. The brook then continues, to join the Birket at Moreton. The Birket, in turn, discharges into the West Float at the site of the former Wallasey Pool.
