Sway is a village and civil parish in Hampshire in the New Forest national park in England. The civil parish was formed in 1879, when lands were taken from the extensive parish of Boldre. The village has shops and pubs, and a railway station on the South West Main Line from Weymouth and Bournemouth to Southampton and London Waterloo. It is the site of Sway Tower, a 66-metre concrete folly built in the 19th century.
