This article refers to the English port of Sharpness. For infomation on other uses of the term "sharpness", see Sharpness (disambiguation).

Sharpness is an English port, one of the most inland in Britain, and 8th largest in the South West.. It is on the River Severn, at a point where the tidal range, though less than at Avonmouth downstream (14m typical 'spring' tide), is still large (10m typical spring).

The Gloucester & Sharpness Canal starts here, and the river used to be crossed here by the Severn Railway Bridge - however, this was damaged beyond repair by a ship collision in 1960.

Just to the south lies the town of Berkeley.

The Port Authority for the impounded dock is British Waterways, but the quayside activities are run by Sharpness Dock Limited. The competent harbour authority (CHA) for the river from the Severn Road Bridges up to Sharpness is Gloucester Harbour Trustees - they are responsible for navigation aids in the channel and for the provision of pilots. Pilotage up the river is compulsory (except for exemption holders) for all vessels over 100 dead weight tons.
