List of number-one songs of 2018 (Mexico)

The airplay chart rankings are published by Monitor Latino, based on airplay across radio stations in Mexico using the Radio Tracking Data, LLC in real time.

Monitor Latino provided two lists for each of these charts: the "Audience" list ranked the songs according to the estimated number of people that listened to them on the radio during the week.

The "Tocadas" (Spins) list ranked the songs according to the number of times they were played on the radio during the week.

"Tu postura" by Banda MS was the best performing song of the year, both by estimated audience and number of spins.

This chart ranks songs that fall under the Regional Mexican category.
