The 2007 West Dunbartonshire Council election was held on 3 May 2007, the same day as the other Scottish local government elections and the Scottish Parliament general election. The election was the first one using six new wards created as a result of the Local Governance (Scotland) Act 2004, each elected three or four councillors using the single transferable vote system form of proportional representation. The new wards replace 22 single-member wards which used the plurality (first past the post) system of election.
