The 1983 West Dorset District Council election was held on Thursday 5 May 1983 to elect councillors to West Dorset District Council in England. It took place on the same day as other district council elections in the United Kingdom. The entire council was up for election, following boundary changes that reduced the number of wards by two, but altogether the number of seats remained the same. Subsequent elections for the council would be elected by thirds following the passing of a resolution under section 7 (4) (b) of the Local Government Act 1972.
The 1983 election saw the Independent councillors lose seats but maintain their majority control on the Council.
