County Buildings was a municipal structure in Garshake Road, Dumbarton, West Dunbartonshire, Scotland.

It was designed by Armstrong Lane, Duncan Bremner, and Alan Bristow of the firm of Lane Bremner & Garnett in the Brutalist style, built in concrete and glass at a cost of £800,000 and was officially opened by Queen Elizabeth II, who was accompanied by the Duke of Edinburgh, on 28 June 1965.

[3] The design involved a five-storey long and narrow main frontage facing onto Garshake Road.

A statue sculpted by James Barclay depicting a mother and child was installed outside the main entrance.

In the early 21st century, the council, finding County Buildings "out of date", "crumbling" and "in the wrong location", decided to commission new offices which were to be erected behind the façade of Dumbarton Burgh Hall.
