Black Dog Halt is a former railway station on the Chippenham and Calne line in Wiltshire, England.

The halt was closed and demolished in 1965, and today it is part of National Cycle Route 403.

Black Dog Halt was opened on 3 November 1863 by the Calne Railway company.

Lord Lansdowne of Bowood House used the halt as a private station; use by the public was allowed, though it was not common knowledge.

Today the site of the halt is being used as part of National Cycle Route 403 which runs from Chippenham to Calne.
