2019–20 Plymouth Argyle F.C. season

The 2019–20 season was Plymouth Argyle's first season back in EFL League Two following relegation the season before and their 134th year in existence. Along with competing in League Two, the club will also participate in the FA Cup, EFL Cup and EFL Trophy. The season covers the period from 1 July 2019 to 30 June 2020.

On 13 March 2020 the season was temporarily suspended, before being indefinitely suspended on 3 April, due to the COVID-19 pandemic. On 15 May, League Two clubs declared their intention to end the season at its current point with immediate effect, with the final table being determined on an unweighted points-per-game basis. The decision meant that Plymouth Argyle, along with champions Swindon Town and Crewe Alexandra would be promoted to League One for the following season.
