St Denys is a partially riverside district of Southampton, England, centred 1.5 miles (2.4 km) north north-east of the city centre facing variously Bitterne Park and quay across the River Itchen estuary. The river is here spanned in the mid-east extreme of the district by Cobden Bridge, one of five within the city's broad boundaries, six including the railway bridge 100 m south. It is separated from the city centre by the districts sometimes known as Bevois Valley and New Town, in turn and to the south a riverside boardwalk allows pedestrian and bicycle access to the Mount Pleasant Industrial Estate and Northam.
