The 2020 Aragon motorcycle Grand Prix (officially known as the Gran Premio Michelin de Aragón) was the eleventh round of the 2020 Grand Prix motorcycle racing season and the tenth round of the 2020 MotoGP World Championship.

The Aragon Grand Prix, scheduled in the original calendar on October 4 as the sixteenth race of the season, was brought forward by a week following the initial postponement of the Thailand Grand Prix (later cancelled on July 31) on the first Sunday in October (the Thailand stage was initially scheduled for 22 March as the second leg of the championship).

Several Grands Prix were cancelled or postponed after the aborted opening round in Qatar, prompting the Fédération Internationale de Motocyclisme to draft a new calendar.

After the ninth round at the 2020 French Grand Prix, Fabio Quartararo leads the drivers' championship with 115 points, with a 5-point advantage over Joan Mir.

In the first session Maverick Viñales was the fastest ahead of Franco Morbidelli and Fabio Quartararo.
