The first presidential debate in Mexico was held on May 12, 1994, almost two months after the assassination of Luis Donaldo Colosio. The formats have evolved from the rigid and stuffy nature of the first meeting in 1994 to a more fluid dynamic like that of the 2018 debates.

From 2000 to 2012, two debates were held before each election and in 2018 there were three. This is a review of the memorable events in some of the 10 meetings between candidates that have been held in the run-up to five elections: 1994, 2000, 2006, 2012 and 2018.
