The following Grands Prix took place in 2021:

• The Finnish Grand Prix was due to be reintroduced to the calendar after a 38-year absence. The venue hosting the round was to be the new Kymi Ring, instead of the Tampere Circuit used in 1962 and 1963, or the Imatra Circuit which hosted the round until 1982. The Finnish Grand Prix had been included on the 2020 calendar, but the inaugural race was cancelled in response to the COVID-19 pandemic.

• The Czech Republic Grand Prix was initially left off the provisional calendar, as the circuit requires mandatory resurfacing for safety compliance, and it was unclear if the necessary work could be completed in time for its typical schedule date in early August. The 11th round of the championship was therefore left open as provisionally pending. On 8 December 2020, Brno city councillors opted out of the 2021 calendar, citing financial difficulties due to the COVID-19 pandemic. It marked the first absence of a Grand Prix in Brno since 1992. The mayor of Brno hopes for the return of the championship in 2022.

• With the uncertainty of the development of the COVID-19 pandemic, championship organizer Dorna elected in November 2020 to nominate three "Reserve Grand Prix Venues" which could be used in the event that local virus containment measures or regulations force the cancellation of a planned Grand Prix.

  • The Portuguese Grand Prix at Algarve had previously returned to the schedule as a replacement race for the final round of the COVID-19 shortened 2020 season.
  • The Indonesian Grand Prix was originally planned to be reintroduced to the main calendar after a 23-year absence before being designated a Reserve Grand Prix for 2021. The venue hosting the round would be the new Mandalika International Street Circuit, instead of the Sentul International Circuit used in 1996 and 1997.
  • A Russian Grand Prix would see the inaugural motorcycle Grand Prix in that country. The Igora Drive circuit would be used.

• On 22 January 2021, Dorna significantly updated the provisional calendar including the following changes:

  • The Argentine and American Grands Prix would be postponed due to the COVID-19 situation in both countries, with potential rescheduling for the final quarter of 2021.
  • A double-header would open the season in Qatar on 28 March and 4 April, followed by Portugal as the third round.
  • The provisionally pending race created by the absence of the Czech Grand Prix was removed.
  • The potential Russian Grand Prix was removed from the reserve list, leaving Indonesia as the sole Reserve Grand Prix Venue.

• On 14 May the Finnish Grand Prix was cancelled due to the COVID-19 situation, and a second Spieiberg race, the Styrian Grand Prix, would replace it on the date of 8 August. It was also confirmed that the Indonesian Grand Prix would remain a reserve Grand Prix in the 2021 calendar, subject to circuit homologation.

• On 23 June the Japanese Grand Prix was cancelled due to the COVID-19 situation, with the previously postponed Grand Prix of the Americas taking its place in the calendar. This also led to the postponement of the Thailand Grand Prix by one week.

• On 6 July the Australian Grand Prix was cancelled due to the COVID-19 situation, with the Malaysian Grand Prix brought forward by a week to replace it on the date of 24 October. In addition, a second race at Algarve, the Algarve Grand Prix, was introduced, which is scheduled to be held on 7 November.

• On 21 July the Thailand Grand Prix was cancelled due to the COVID-19 restrictions in the country.

• On 19 August the Malaysian Grand Prix was cancelled due to the COVID-19 restrictions in the country. For its replacement, a second Grand Prix at Misano was introduced, having the same schedule as the cancelled Malaysian round.

• On 11 September the final championship calendar comprising 18 Grands Prix was confirmed. The Emilia Romagna and Rimini Riviera Grand Prix returned as the second Grand Prix at Misano, now having the shortened name of Emilia Romagna motorcycle Grand Prix. The previously postponed Argentine Grand Prix was also cancelled.
