The 2021 NASCAR PEAK Mexico Series was the fourteenth season of the NASCAR PEAK Mexico Series, a regional stock car racing series sanctioned by NASCAR in Mexico. It was the seventeenth season of the series as a NASCAR-sanctioned series. It began with the race at Súper Óvalo Chiapas on 23 May and ended with the race at Autódromo Miguel E. Abed on 5 December.
Salvador de Alba Jr. won his first championship in the series, prevailing in a tight points battle he and three-time series champion Rubén García Jr. had during the season. Both of them as well as two-time series champion Abraham Calderón, defending series champion Rubén Rovelo, and José Luis Ramírez won races in 2021.
This was the last year that PEAK (and parent company Old World Industries) was the title sponsor of the series. In 2022, the name of the series changed to the NASCAR Mexico Series after a replacement title sponsor was not found.
