Blackwater is a town in the Hart District of Hampshire, England. It forms part of the Farnborough/Aldershot Built-up Area and almost is contiguous with Camberley. Blackwater is 32 miles (51 km) from London.
A pre-1900 distance sign near the nightclub on the A30, in Camberley marks "London - 30 miles", from which the centre of Blackwater is less than a mile.
The town is in the outer half of the London Commuter Belt, the fastest link being Farnborough (Main) Station on the South Western Main Line. The place sits west of where the A30 trunk road from London to Land's End crosses the River Blackwater. It is served by Blackwater railway station which is on the non-interchanging line, midway, between Reading and Guildford.
