Grupo Firme is a Mexican regional band formed in Tijuana that rose to prominence in the late 2010s and early 2020s. They perform primarily within the banda and norteño-sierreño styles of regional Mexican music, often incorporating elements of corridos, ranchera, and modern pop-influenced arrangements. Known for energetic live performances and vocal-driven arrangements featuring brass, accordion or twelve-string guitar textures depending on the lineup, their repertoire includes both romantic ballads and upbeat dance numbers. Their music emphasizes melodic hooks, emotive lead vocals and a production approach that blends traditional instrumentation with contemporary recording techniques, making them a significant presence in contemporary regional Mexican popular music.
