- River: Avon, at Aish near South Brent
- Grid reference: SX 695 606
- Date: probably 17th or 18th century; in decay in 1669, so the present bridge is a restoration or rebuild
- Designation: Grade II, Historic England list entry 1307206 (listed 27 May 1986)
Lydia Bridge is a single humped arch in stone rubble, widened on the upstream side, probably a 17th or 18th-century packhorse bridge. It was recorded as in decay in 1669 (Henderson and Jervoise, Old Devon Bridges), so what stands now is a rebuild or restoration.
A small waterfall, Lydia's Falls, lies just upstream. Old guides send walkers from South Brent over Lydia Bridge to Aish and Didworthy, and Eden Phillpotts sets a cottage by it in Children of Men. We have found no source for the name and do not offer one.

This bridge is one of the crossings gathered in Dartmoor Bridges, a guide to the clapper bridges, packhorse bridges and road bridges of the moor and its edge.
