FAIM, short for Fábrica Argentina de Instrumentos Musicales, is an Argentine builder of electric guitars and basses. The company began producing electric guitars in the early 1960s and expanded into basses in the 1970s, becoming one of the most recognizable domestic instrument brands in Argentina alongside makers like Kuc.

FAIM's catalog has historically been built around accessibly priced takes on classic international designs, including Les Paul–style, SG-style, Telecaster-style, Stratocaster-style, and Musicmaster-style guitars, as well as a range of bass models. Instruments from the 1980s and early 1990s are commonly built with native Argentine woods such as guatambú necks and lenga bodies, paired with locally sourced hardware and pickups.

Because Argentina's import restrictions through much of the late 20th century encouraged a self-contained domestic instrument industry, FAIM guitars and basses developed a following among Argentine players and have since become a point of interest for vintage collectors looking at South American–made gear.

Faim has 5 products cataloged on Equipboard, including Electric Basses, Semi-Hollowbody Electric Guitars, and Solid Body Electric Guitars. Their gear is featured by 3 artists, with the strongest followings in Rock, Metal, and Folk, World, & Country. Notable users include Pedro Aznar, Ricardo Iorio, and Marcelo Corvalán.
