Swanwick (/ˈswɒnɪk/) is a village in Hampshire, England, east of the River Hamble and north of the M27 motorway. The village is located within the borough of Fareham and is the site of the London Area Control Centre (LACC) and the London Terminal Control Centre (LTCC), part of National Air Traffic Services Air Traffic Control Centre, and Bursledon Brickworks, the last remaining example of a Victorian steam-powered brickworks.
Swanwick has no real village centre and the only commercial premises of note is the Elm Tree Public House. Since the 1980s, the gradual spread of housing developments has meant that Swanwick has partly merged with the new development of Whiteley although the only direct vehicular access is via Yew Tree Drive (once a bus only route).
Swanwick railway station on the West Coastway Line is approximately one mile south of the village and is nearer Park Gate than Swanwick.
The village's "twin" Lower Swanwick is situated two miles west of the village on the edge of the River Hamble.
