The 1991 West Dorset District Council election was held on Thursday 2 May 1991 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. District boundary changes took place before the election but the number of seats remained the same.[1]
The 1991 election saw the council remain in no overall control, with Independent councillors maintaining their status as the largest group.
