2019–20 London City Lionesses F.C. season

The 2019–20 London City Lionesses F.C. season was the club's first season in existence following a breakaway from Millwall Lionesses in May 2019. The team competed in the FA Women's Championship, the second level of the women's football pyramid, as well as two domestic cup competitions: the FA Cup and the League Cup.

On 13 March 2020, in line with the FA's response to the coronavirus pandemic, it was announced the season was temporarily suspended until at least 3 April 2020. After further postponements, the season was ultimately ended prematurely on 25 May 2020 with immediate effect. London City Lionesses sat in 4th at the time and retained their position on sporting merit after The FA Board's decision to award places on a points-per-game basis.
