Strathkelvin and Bearsden is a county constituency of the Scottish Parliament covering part of the council area of East Dunbartonshire. 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 West 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 seat has been held by Rona Mackay of the Scottish National Party since the 2016 Scottish Parliament election.
The other nine constituencies of the West Scotland region are: Clydebank and Milngavie, Cunninghame North, Cunninghame South, Dumbarton, Eastwood, Inverclyde, Paisley, Renfrewshire North and Cardonald, and Renfrewshire West and Levern Valley. The region covers the whole of the council areas of East Dunbartonshire, East Renfrewshire, Inverclyde, North Ayrshire, Renfrewshire, and West Dunbartonshire; and parts of the council areas of Argyll and Bute, East Ayrshire, and Glasgow.
The Strathkelvin and Bearsden constituency was created at the same time as the Scottish Parliament, for the 1999 Scottish Parliament election, with the name and boundaries of the existing Strathkelvin and Bearsden constituency of the UK House of Commons. Ahead of the 2005 United Kingdom general election the House of Commons constituencies in Scotland were altered, whilst the existing Scottish Parliament constituencies were retained, and there is now no longer any link between the two sets of boundaries. The boundaries of the seat were altered slightly by the First Periodic Review of Scottish Parliament Boundaries in 2011, but were left unchanged at the Second Periodic Review of Scottish Parliament Boundaries in 2025.
The rest of East Dunbartonshire is represented by the Clydebank and Milngavie constituency.
