Thames Gateway is a term applied to an area around the Thames Estuary in the context of discourse around regeneration and further urbanisation. The term was first coined by the UK government and applies to an area of land stretching 70 kilometres (43 mi) east from inner east and south-east London on both sides of the River Thames and the Thames Estuary. It stretches from Westferry in Tower Hamlets to the Isle of Sheppey/Southend-on-Sea and extends across three ceremonial counties.
