Schedule
The schedule was initially announced on October 28, 2020, and features 14 rounds across seven double-header weekends. On December 17, 2020, the schedule was revised, along with the 2021 WeatherTech SportsCar Championship schedule, due to the ongoing COVID-19 pandemic.

On January 6, 2021, the St. Petersburg event was rescheduled from its March date to April 23–25, due to the COVID-19 pandemic.

On February 8, 2021, IMSA announced an additional double-header event to be held during the 12 Hours of Sebring event weekend in March. Rounds 3 and 4 at Sebring will serve as a replacement for a future race venue to be announced at a later date. Thus, the 2021 MX-5 Cup Championship will still be composed of 14 rounds at seven tracks.

On April 7, 2021, the Canadian Tire Motorsport Park event scheduled for July 2-4 was cancelled due to COVID-19 quarantine requirements.
