The Tavy (/ˈteɪvi/) is a river on Dartmoor, Devon, England. The name derives from the Brythonic root "Tam", once thought to mean 'dark' but now generally understood to mean 'to flow'.^[1] It has given its name to the town of Tavistock and the villages of Mary Tavy and Peter Tavy.

It is a tributary of the River Tamar and has as its own tributaries: Collybrooke, River Burn, River Wallabrooke, River Lumburn, and River Walkham. At Tavistock it feeds a canal running to Morwellham Quay.

Its mouth is crossed by the Tavy Bridge which carries the Tamar Valley railway line.
