Kincaidston is a housing scheme in the town of Ayr in South Ayrshire, Scotland.

It was built by Kyle and Carrick District Council and Digital Equipment Corporation to house workers for a nearby factory development.

Most of the streets are named after flowers (for example, Celandine Bank, Honeysuckle Park and Speedwell Square) apart from Kincaidston Drive, the estate's main road.

During World War I, a Sopwith Camel crashed at the farm, killing the pilot, Captain Victor George Anderson Bush, who had been based at No.1 School of Aerial Fighting at Turnberry.

On 18 October 2021, four people were injured in an explosion that destroyed a house on Gorse Park and damaged multiple others.
