Restronguet Creek is a tidal ria in south Cornwall, United Kingdom. It is a tributary of Carrick Roads, the estuary of the River Fal, and is situated approximately four miles (6.5 km) south of Truro and three miles (5 km) north of Falmouth. 〔Ordnance Survey: Landranger map sheet 204 ''Truro & Falmouth'' ISBN 978-0-319-23149-4〕 The creek is approximately two miles (3 km) long from its Normal Tidal Limit (NTL) to its mouth and half-a-mile (800 metres) across at its widest point. It discharges into Carrick Roads at Restronguet Point through a narrow channel〔 known locally as 'the gut'.〔() Restronguet Creek Society website.

The NTL on the Carnon River is immediately upstream of Devoran where the A39 trunk road crosses the river; the NTL on the River Kennall is at Perran Wharf.〔Ordnance Survey: Explorer map sheet 104 ''Redruth & St Agnes'' ISBN 978-0-319-46719-0〕 A smaller stream from the north discharges into the tidal creek at Penpol. ==Industrial past== Until the beginning of the 20th century, Restronguet Creek (and its tributary rivers) played an important role in the tin and copper mining industry. Devoran was a small port engaged in the export of mined minerals and the import of mining materials and coal. The Redruth and Chasewater Railway, an early industrial line which served the many mines a few miles to the north, terminated at Devoran (although there was an extension to Point Quay on Restronguet Creek; trains were hauled by horses rather than locomotives on the extension). There were also wharves and quays at the head of Penpol Creek. At low water, large expanses of intertidal mudflats are exposed (which can be dangerous because the mud is deep and very soft〔〔() Exeter University; Camborne School of Mines website; Fal estuary location notes. Retrieved June 2010〕) and recent academic study suggests the mud still bears evidence of mineral contamination by former mining activity further upstream.〔() Exeter University; Camborne School of Mines website; ''Mapping and visualisation of historical mining contamination in the Fal Estuary''.
