The 2020 All-Ireland Junior Ladies' Football Championship was the 38th contested edition of the Ladies' Gaelic Football Association's tertiary inter-county Ladies' Gaelic football tournament.

The impact of the COVID-19 pandemic on Gaelic games forced the delay of the tournament until late in the year.
