Elections to Wiltshire County Council were held on 6 May 1993. The whole council was up for election and the result was no overall control, with the Liberal Democrats as the largest party. This resulted in a no-party-control shared administration for the first year of the Council, with the three main party groups being briefed on a coequal basis. Following a by-election gain by the Liberal Democrats from the Conservatives, giving the Liberal Democrats exactly half the seats on the Council, a Liberal Democrat administration was formed, but with a convention that committee chairpersons would not use their casting vote to force through policies.
