Hampshire County Cricket Club is one of eighteen first-class county clubs within the domestic cricket structure of England and Wales. It represents the historic county of Hampshire. Hampshire teams formed by earlier organisations, principally the Hambledon Club, always had first-class status and the same applied to the county club when it was founded in 1863. Because of poor performances for several seasons until 1885, Hampshire then lost its status for nine seasons until it was invited into the County Championship in 1895, since when the team have played in every top-level domestic cricket competition in England. Hampshire originally played at the Antelope Ground, Southampton until 1885 when they relocated to the County Ground, Southampton until 2000, before moving to the purpose-built Rose Bowl in West End, which is in the Borough of Eastleigh. The club has twice won the County Championship, in the 1961 and 1973 seasons.

Inter-county cricket matches have been played since the early 18th century, involving teams that are representative of the historic counties of England and Wales. Since the late 19th century, there have been two county championship competitions played at different levels: the County Championship, a first-class competition which involves eighteen first-class county clubs among which seventeen are English and one is from Wales; and the National Counties Championship, which involves nineteen English county clubs and one club that represents several Welsh counties.
