2019–20 Southern Football League

The 2019–20 Southern Football League season (known as the BetVictor Southern League, following a sponsorship deal with BetVictor) was the 117th in the history of the Southern League since its establishment in 1894. The league has two Premier divisions (Central and South) at step 3 of the National League System (NLS) and two Division One divisions (Central and South) at step 4 of the NLS. These correspond with Levels 7 and 8 of the English football league system.

As a result of the COVID-19 pandemic, this season's competition was formally abandoned on 26 March 2020, with all results from the season being expunged, and no promotion or relegation taking place to, from, or within the competition. On 30 March 2020, sixty-six non-league clubs sent an open letter to the Football Association requesting that they reconsider their decision. A legal appeal against the decision, funded by South Shields of the Northern Premier League, was dismissed in June 2020.
