The 2011 Mansfield District Council election took place on 5 May 2011 to elect members of Mansfield District Council in Nottinghamshire, England. The whole council was up for election as was the directly- elected executive mayor. The ward boundaries were reorganised, reducing the number of members from 46 (spread over the previous 19 wards) to 36 single-member wards. Re-aligning the wards by considering geographical area and housing density reflected a more-even number of voters per ward.
