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 used the six wards created under the Local Governance (Scotland) Act 2004, with 22 Councillors being elected. Each ward elected either 3 or 4 members, using the STV electoral system.
The election saw Labour gain 2 seats to secure an overall majority on the Council while also significantly increasing their vote. The Scottish National Party remained in second place on the Council but West Dunbartonshire proved to be their worst performance in Scotland as they lost 3 seats including that of Council leader Ronnie McColl. Independents increased their seat numbers to 3 through the addition of former Labour Councillor and the Scottish Socialist Party retained their sole seat - their only one in Scotland.
Following the election the Labour majority administration was formed. This replaced the previous SNP minority led administration which had been supported by Independent councillors that had existed from 2007-2012.
Note: "Votes" are the first preference votes. The net gain/loss and percentage changes relate to the result of the previous Scottish local elections on 3 May 2007. This may differ from other published sources showing gain/loss relative to seats held at dissolution of Scotland's councils.
