List of top-ten songs in 1948 and 1949 (Mexico)

These are the monthly charts of the top-ten most popular songs in Mexico between September 1948 and December 1949 according to the magazine Selecciones Musicales and as compiled in the book Musicosas: manual del comentarista de radio y televisión by Roberto Ayala. These charts were based on record sales, jukebox plays, radio and television airplay, and sheet music sales.

As published in the Musicosas book, the charts only include the song titles and the names of the composers; the performers credited in this article are included for reference and where many performers are listed for the same song, they appear in alphabetical order, which may not reflect whose version was the most popular.
