Waterlooville is a town in Hampshire, England just north of Portsmouth.

The town, located in the borough of Havant, has a population itself of about 10,000 and has surrounding villages such as Purbrook, Cowplain, Denmead , Hambledon, Horndean, Hart Plain and Widley. It forms part of the South Hampshire conurbation. The old A3 London to Portsmouth road still goes through the town.

Legend has it that it was named after the pub that stood at the centre of town. The Heroes of Waterloo was named because on its opening day a long column of weary soldiers, who had just disembarked at Portsmouth returning home from the Battle of Waterloo in 1815, decided to stop there and celebrate their victory. According to local legend, many of them settled there; at any rate the pub was renamed in their honour and the area around the pub became known as Waterlooville.

The original "Heroes" pub was at a crossroads near the main bus-stop. The new pub has taken the name but is in a different location.
