Sunrisers are a women's cricket team that represent the London and East region, one of eight regional hubs in English domestic women's cricket. They play their home matches at various grounds, including the County Cricket Ground, Chelmsford. They are captained by Grace Scrivens in the Rachael Heyhoe Flint Trophy and Dane van Niekerk in the Charlotte Edwards Cup, and are coached by Andy Tennant. The team is partnered with Middlesex, Essex, Northamptonshire, Hertfordshire, Cambridgeshire, Suffolk, Norfolk, Bedfordshire and Huntingdonshire, as well as Marylebone Cricket Club.

The Rachael Heyhoe Flint Trophy is an English and Welsh women's cricket domestic competition, named after former England captain Rachael Heyhoe Flint, Baroness Heyhoe-Flint, who died in 2017. The first edition of the tournament took place during August and September 2020, with the Southern Vipers beating the Northern Diamonds in the final. Initially started as a one-off tournament, in February 2021 the England and Wales Cricket Board (ECB) announced it would return for the 2021 season as a permanent part of the women's domestic structure in England and Wales, alongside the Charlotte Edwards Cup.
