Belthorn is a small moorland village situated to the south-east of Blackburn in Lancashire, England.

It is about two-thirds of a mile (1.1 km) away from junction 5 of the M65 motorway, which runs from Colne to Preston.

The village has two pubs: the community-owned, recently reopened Dog Inn and the Pack Horse (now named Marco Polo); the Pack Horse is an Italian restaurant and the Dog Inn serves pub food.

The village is divided between the unitary authority of Blackburn with Darwen and the district of Hyndburn, both of which have borough status.

The portion of the village within Blackburn with Darwen is largely within the ancient parish (now a civil parish) of Yate and Pickup Bank, with a small area in the north of the village, formerly in the parish of Lower Darwen.
