Southwick is a semi-rural village and civil parish 3 miles (4.8 km) south-west of the county town of Trowbridge, Wiltshire, England.

It is separated from the south-west fringe of Trowbridge only by the Southwick Country Park, which consists of 380 acres (150 ha) of open fields.

In Flemish bond brick with limestone dressings, the gothic-style building has a clock tower with a short octagonal stone spire.

A chapel linked to the Conigre church at Trowbridge stood near Bradley Common throughout the 18th century, and in 1709 another was built on the south side of Wynsome Street, which soon had a congregation of 300.

A revival here led to the building of a replacement chapel in 1815, in red brick with stone dressings, under a slate roof.

[9] Nearby to the north-west, where the road crosses the Lambrok Stream, is an open-air baptistery, rebuilt in stone in 1937 and described by Historic England as "a rare surviving example",[10] although Pevsner states the stonework to be of "suburban character".

Inside is a wooden chancel screen in Arts and Crafts style, and an immersion tank for baptism, in keeping with Southwick's Baptist tradition.

[4] In the Middle Ages there was a family chapel nearby, dedicated to St John the Baptist; this fell into disuse sometime after 1544 and the building was demolished in 1839.

It is in the area of Wiltshire Council unitary authority, which is responsible for all significant local government functions.

[20] There are two main residential areas in the north-east of the village, opposite the Southwick Allotments and the 'Farmhouse Inn' pub.
