The Beaulieu River, formerly known as the River Exe, is a small river draining much of the central New Forest in Hampshire, southern England. The river has many small upper branches and its farthest source is 8 miles (13 km) from its 4 miles (6 km)-long tidal estuary. Unusually, the river, including its bed, is owned by Lord Montagu of Beaulieu.
