The 2012 West Dunbartonshire Council election was held on 3 May 2012 on the same day as the 31 other local authorities in Scotland.

The election saw Labour gain 2 seats to secure an overall majority on the Council while also significantly increasing their vote.

This replaced the previous SNP minority led administration which had been supported by Independent councillors that had existed from 2007-2012.

This may differ from other published sources showing gain/loss relative to seats held at dissolution of Scotland's councils.

On 5 January 2016, Marie McNair joined the Scottish National Party and ceased to be an independent.
