2012 Elections to Scottish Borders Council were held on 3 May 2012, the same day as the other Scottish local government elections. The election used the 11 wards created as a result of the Local Governance (Scotland) Act 2004, with each ward electing three or four Councillors using the single transferable vote system, a form of proportional representation, with 34 Councillors elected.

The election saw the Scottish Conservative Party remain the largest party on the Council though they lost 1 seat. The Scottish National Party replaced the Scottish Liberal Democrats as the second largest party by gaining 3 seats at the expense of the latter. The Lib Dems were reduced to 6 seats. Independents increased their numbers to 7 seats while the Borders Party retained their 2 seats.

Following the election the Scottish National Party formed a coalition with the support of the Independents and the Liberal Democrats. The Borders Party are also supporting this administration. This replaced the previous Conservative-Lib Dem-Independent coalition which 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.
