Gracia is an Argentine guitar maker based in Buenos Aires with roots tracing back to the Antigua Casa Núñez lineage. The Gracia family entered the business in 1925 when Dionisio Gracia and relatives took over Don Francisco Núñez's workshop, and by the 1960s the operation had become Antigua Casa Núñez SA, with Arístides Gracia serving as its principal luthier until the company was sold in 1992. Arístides continued building under his own name, and the workshop is now directed by Ariel Alegre, an apprentice of Arístides who leads the current team out of the Boedo district of Buenos Aires.

The shop produces instruments under two lines: Marca Gracia, the heritage line focused on nylon-string classical guitars and select steel-string acoustics, and Marca AG, a contemporary line covering electric guitars, basses, electroacoustics, and amplifiers. The classical M-series (M2, M3, M5, M7) is a long-running staple, and the AG line builds models inspired by Stratocaster, Telecaster, Les Paul, SG, PRS, 335, and Rickenbacker shapes, alongside jumbo acoustics and custom builds.

Gracia instruments are widely used by students and working musicians across Argentina and the broader Spanish-speaking world, where the brand is recognized as one of the more established names in domestic guitar making. Each instrument is hand-finished, calibrated, and set up in-house before shipping.

Gracia has 6 products cataloged on Equipboard, including Acoustic-Electric Guitars, Classical & Nylon-String Guitars, and Solid Body Electric Guitars. Their gear is featured by 2 artists, with the strongest followings in Latin, Rock, and Pop. Notable users include Gabriel Orozco and Manuel Rodriguez.
