The 2011 elections to Cheshire West and Chester Borough Council were the first elections to this Council after it had been re-warded into a mixture of single-, two- and three-member wards. They took place on 5th May alongside the 2011 United Kingdom Alternative Vote referendum. The previous election held for 2008 were based on the old Cheshire County Council electoral divisions each of which returned 3 members. The 2008 elections elected 72 members to serve first on the shadow authority and then, with effect from 1 April 2009, the new Council when it took over responsibility for the delivery of local government services.
