Broadwater is a neighbourhood of Worthing, in the borough of Worthing in West Sussex, England. Situated between the South Downs and the English Channel, Broadwater was once a parish in its own right and included Worthing when the latter was a small fishing hamlet. Before its incorporation into the Borough of Worthing in 1902 Broadwater also included the manor of Offington to the north. It borders Tarring to the west, Sompting to the east, and East Worthing to the south-east.
