The River Huntspill is an artificial river, in the Somerset Levels, in the Sedgemoor district of Somerset, England. It was built in 1940 to supply process water to ROF Bridgwater, and has resulted in reduced flooding of the lower Brue Valley. Huntspill Sluice at the river's western end, also known as West Huntspill Sluice, separates it from the River Parrett.
