Billboard Latin Music Award for Hot Latin Song of the Year

The Billboard Latin Music Award for Hot Latin Song of the Year (formerly Hot Latin Track of the Year) is an honor presented annually at the Billboard Latin Music Awards, a ceremony which honors "the most popular albums, songs, and performers in Latin music, as determined by the actual sales, radio airplay, online streaming and social data that informs Billboard's weekly charts." The award is given to the best performing singles on Billboard's Hot Latin Songs chart, which measures the most popular Latin recordings in the United States. The Hot Latin Songs chart was established by the magazine in September 1986 and was originally based on airplay on Latin music radio stations. Since October 2012, chart rankings are based on digital sales, radio airplay, and online streaming. From 1995 to 1998, each music genre's field (pop, tropical/salsa and Regional Mexican) had their own Hot Latin Track of the Year category.

Enrique Iglesias and Nicky Jam are the most awarded acts in the category with three wins each. Alejandro Fernández, Wisin & Yandel, Don Omar, Romeo Santos, Ozuna, Nicky Jam, Peso Pluma and Grupo Frontera are the only acts with two nominated songs in the same year, a milestone achieved twice by Santos. Bad Bunny became the only act to have three nominated songs in the same year. As of 2017, only Iglesias and Nicky Jam have won Hot Latin Song of the Year twice in a row. As of 2023, the holders are Eslabon Armado and Peso Pluma for the song "Ella Baila Sola". Enrique Iglesias and Bad Bunny became tied for the most nominations as of 2023.
