Fleet is a town and civil parish in the Hart District of Hampshire, England, centred 38.2 miles (61.5 km) WSW of London and 13 miles (21 km) east of Basingstoke. It is the major town of the Hart District, and has large technology business areas, fast rail links to London, and is well connected to the M3. The Fleet built-up area has a total population of 42,835, and includes the contiguous parishes of Church Crookham, Crookham Village, Dogmersfield, and Elvetham Heath. The town has a prominent golf club, an annual half marathon, an athletics club, and four football clubs. The nearby service station on the motorway is named after the town.
Hart, of which Fleet is the main town, was voted the best place to live in the UK by the Halifax Quality of Life study in 2011, 2012, 2013, 2014, 2015, and again in 2017, above areas such as Elmbridge in Surrey and Wokingham in Berkshire. This is due to the highly affluent majority of the population, better weather and health conditions, high levels of access to leisure space, and the town's surrounding countryside which includes woodlands and the Basingstoke Canal.
Local landmarks include Fleet Pond, the largest freshwater lake in Hampshire, and a High Street with many Victorian and Edwardian buildings. Fleet holds a weekly Saturday market in Gurkha Square.
