Low Wood Gunpowder Works (also Lowwood) was a gunpowder mill founded in Furness, England, at the end of the 18th century. It became a significant supplier, and survived as a business until taken over by Imperial Chemical Industries around 1930. The works has been disused since 1935. The mill was set up on an estuary site, for sea access, on the River Leven. Initially it was called Daye Barker & Co., the founding partners being Daye Barker, James King, Christopher Wilson and Joseph Fayrer. The surviving Clock Tower Works is a Grade II* Listed Building.
