"Lost Lionesses" is a name retroactively applied to the first women's football team to represent England at a major international tournament, the 1971 Women's World Cup in Mexico. Being unofficial, unrecognised, and disbanded shortly after their return to England, the team was largely overlooked for nearly 50 years, first gaining widespread media coverage in England in 2019. The team called themselves the British Independents, but were billed as "Inglaterra" during the competition.
