Yeolmbridge is a village in Cornwall, historically in Devon, two and a half miles north of Launceston.
Yeolm Bridge over the River Ottery is Grade I listed and a Scheduled Ancient Monument. Built about 1350, it is considered the oldest surviving and best built of medieval Cornish bridges. Nikolaus Pevsner described it as Cornwall's "most ambitious" bridge.
Yeolmbridge Quarry SSSI is 250 m to the east of the village. The quarry is designated a Site of Special Scientific Interest and a Geological Conservation Review (GCR) site, as the type–locality of the Yeolmbridge Formation; a black shale which shows the Devonian–Carboniferous boundary around 359 million years ago with a sequence of fossils.
- Joan Rendell, an English historian, writer and phillumenist, was resident at Yeolmbridge in the latter part of her life.
