Ettrick, Roxburgh and Berwickshire

Ettrick, Roxburgh and Berwickshire (Gaelic: Eadraig, Rosbrog agus Siorrachd Bhearaig) is a county constituency of the Scottish Parliament covering part of the council area of Scottish Borders. Under the additional-member electoral system used for elections to the Scottish Parliament, it elects one Member of the Scottish Parliament (MSP) by the first past the post method of election. It is also one of ten constituencies in the South Scotland electoral region, which elects seven additional members, in addition to the ten constituency MSPs, to produce a form of proportional representation for the region as a whole.

The constituency was established for the 2011 Scottish Parliament election, and covers parts of the former constituencies of Tweeddale, Ettrick and Lauderdale and Roxburgh and Berwickshire. The remaining parts of the Scottish Borders form part of the Midlothian South, Tweeddale and Lauderdale constituency. The boundaries of the constituency remained unchanged following the Second Periodic Review of Scottish Parliament Boundaries undertaken by Boundaries Scotland ahead of the 2026 Scottish Parliament election.

Ettrick, Roxburgh and Berwickshire is currently held by the Conservatives. The current MSP is Rachael Hamilton, who won the seat at a 2017 by-election following the resignation of previous member John Lamont in order to contest the 2017 UK general election.
