Lea Bridge is a district in the London Borough of Hackney and the London Borough of Waltham Forest in London, England. It lies 7 miles (11.3 km) northeast of Charing Cross. The area it takes its name from a bridge built over the River Lea in 1745, and the Lea Bridge Road which leads through the area and across the bridge. The bridge also gives its name to a ward in Waltham Forest (Lea Bridge) on the eastern, Leyton, bank of the river, and to a ward in Hackney on the Western side of the river, also called Lea Bridge ward. The boundary between the two boroughs runs down the middle of the river at this point.
