Ramírez is a Spanish luthier house founded in Madrid in 1882 by José Ramírez I, when he opened a guitar-making workshop on Calle Cava Baja. Now run by the fifth generation of the family, the company builds handcrafted classical and flamenco guitars and is regarded as one of the foundational names in the Spanish concert-guitar tradition.

The catalog is organized into hand-built Artisan instruments (made from woods aged for decades in the family workshop) and the more accessible Studio line. Signature models include the Traditional, developed by José Ramírez III in the 1960s in collaboration with Andrés Segovia; the Tablao, designed for flamenco performers seeking greater projection; and the Mangoré and Manuel Ramírez models, replicas of historically significant instruments associated with Agustín Barrios and Segovia. Special editions such as the 125th Anniversary guitar have also been produced in limited runs.

Ramírez instruments have been played by a long list of notable guitarists across classical, flamenco, and rock, including Andrés Segovia, Agustín Barrios, Manuel Barrueco, Eric Clapton, George Harrison, and Carlos Santana.

Ramirez has 6 products cataloged on Equipboard, including Classical & Nylon-String Guitars. Their gear is featured by 6 artists, with the strongest followings in Rock, Folk, World, & Country, and Blues. Notable users include Mark Knopfler, Steve Stevens, and Peter Green.
