Originally created in 1974, the ward was initially within Cumnock and Doon Valley District Council before the local government reforms in the 1990s.
The ward was a Labour stronghold as the party successfully held the seat at every election from 1977 until it was abolished.
The Drongan, Ochiltree, Rankinston and Stair ward was created in 1974 by the Formation Electoral Arrangements from the previous Stair and Ochiltree electoral division and the Littlemill polling district of Ayr County Council.
The ward took in a rural area around the villages of Drongan, Ochiltree, Rankinston and Stair and took in an area in the west of Cumnock and Doon Valley next to its border with Kyle and Carrick District Council.
