Northam is a suburb of Southampton in Hampshire. On the West bank of the River Itchen, it shares borders with St Mary's, Bitterne and Bevois Valley. Beside the border with St Mary's is the Chapel area, which has been home to some recent apartment building developments in Northam. The A3024 road runs through the suburb and crosses the Northam Bridge, which links Northam with Bitterne via Bitterne Manor. Although St Mary's Stadium takes its name from the neighbouring St Mary's, the stadium itself is in Northam, and home to Southampton F.C.
