2019–20 Essex Senior Football League

The 2019–20 season was the 49th in the history of Essex Senior Football League, a football competition in England.

The provisional club allocations for steps 5 and 6 were announced by the FA on 19 May 2019. The constitution was ratified by the league at its AGM.

Due to the coronavirus pandemic, and in line with directives from The FA, the Essex Senior League issued a statement on 16 March confirming the postponement of forthcoming matches. 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.

The league featured 16 clubs which competed in the division last season, along with three new clubs:
 * Cockfosters, transferred from the Spartan South Midlands League
 * Hadley, transferred from the Spartan South Midlands League
 * Hashtag United, promoted from the Eastern Senior League
