Melbury Abbas is a village and civil parish in north Dorset, England, situated between Shaftesbury and Blandford Forum on the edge of Cranborne Chase, close to Melbury Down. The village has a population of 301 (2001), 34.4% are retired. 6.1% of dwellings are second homes.
The village is situated on what has become the main road between Shaftesbury and Blandford. This road runs along the hills of Cranborne Chase and is not officially classified, but is used by much of the traffic that should use the A350 primary route which runs in a roughly parallel course through the Blackmore Vale less than a mile to the west. This is because the hilltop road is straighter and passes through fewer villages. Melbury Abbas is the only bottleneck on this road, where it dips down into the valley and becomes narrower. Dorset County Council have considered bypass schemes, but none have got further than preliminary stages as the village is surrounded by important conservation land.
