The RiverLoddon is a river in the English counties of Berkshire and Hampshire.
It is a tributary of the River Thames, rising within the urban area of Basingstoke and flowing to meet the Thames near the village of Wargrave.
The catchment area of the RiverLoddon encompasses urban populations in Basingstoke and eastern Reading, whilst the urban areas of Aldershot, Fleet, Camberley and Farnborough all lie within the catchment area of the tributary River Blackwater.
However, Seven Springs near Cheltenham, where the river Churn rises, is also sometimes quoted as the Thames' source, as this location is furthest from the mouth both in distance along its course and as the crow flies.
This tidal stretch of the river is known as "the Tideway".
Between the sea and Teddington Lock, the river forms part of the Port of London and navigation is administered by the Port of London Authority.
