Gulargambone is a small town in the central-west plains of New South Wales, Australia, on the banks of the Castlereagh River, in Coonamble Shire.

The town came to national attention in 2000, when the local government attempted to close down the post office, leading to the opening of the first community-owned post office in Australia, which has been followed by a number of other community-led initiatives.

These include the improvement of the local hospital, creating a multi-purpose health centre, the opening of a new cinema and the transformation of the old cinema, Simmo's Bazaar, into 2828, the community centre, featuring a café and a gift shop.

Driving by car from Dubbo to Gulargambone is 114 km and takes roughly 1.25 hr.
