The Anglian Water Authority was a British regional water authority that served the East Anglia region. It was formed in 1974 by virtue of the Water Act 1973 as one of the regional water authorities.
It established its headquarters in Huntingdon in Cambridgeshire. The authority boundary was the pre-existing boundaries of the constituent river authorities whose total area made Anglian Water Authority the largest of the ten newly created Authorities. It was privatised in 1989, to create Anglian Water which took over many of its assets and responsibilities, the remainder being vested in the Environment Agency.
