Southwick is a former village and now a suburb on the north banks of the River Wear in Sunderland, in the county of Tyne and Wear, England, historically in County Durham.

From 1894 to 1928, Southwick was administered by the Southwick-on-Wear Urban District Council,[2] before being absorbed by Sunderland.

Southwick borders with Castletown and Hylton Red House to the west, Monkwearmouth to the east, greenbelt farmland and the suburb of Carley Hill to the north, and the Wear to the south although the Queen Alexandra Bridge links Southwick to Pallion and central Sunderland.

Southwick is centered on its village green, a commercial area containing three listed buildings; a World War II war memorial, The Tramcar Inn a public house built in 1906, and a memorial lamp-post built in 1912.

At the time of a company merger with Austin's in 1954 the yard was redeveloped at a cost of £3 million.
