Admira is a Spanish guitar manufacturer based in Zarautz, a coastal town in Gipuzkoa in northern Spain. The company traces its roots to 1944, when German émigré Enrique Keller Fritsch founded the parent business that would later launch the Admira brand in 1968 and begin producing acoustic guitars in 1980. Run across multiple generations of the Keller family, the workshop combines traditional Spanish lutherie with modern manufacturing methods, and has produced more than three million instruments distributed worldwide.

The company specializes in nylon-string classical guitars, with its catalog also covering flamenco models, electro-classical guitars, and the Admira Acoustics steel-string line. Well-known instruments include the entry-level Alba and Juanita student models, the mid-tier Sevilla and Málaga, and higher-end solid-top models such as the Virtuoso, Artista and the all-solid Hand-Crafted series. The Admira Crossover combines a classical neck with a cutaway acoustic body for players bridging styles.

Admira is widely associated with affordable, accessible Spanish-built classical guitars and is one of the more commonly recommended brands for beginning and intermediate classical students, while its solid-wood models are aimed at advanced players and teachers.

Admira has 28 products cataloged on Equipboard, including Classical & Nylon-String Guitars. Their gear is featured by 7 artists, with the strongest followings in Rock, Pop, and Folk, World, & Country. Notable users include Mauricio Durán, Rex Orange County, and Stephin Merritt. Most Admira products fall in the mid-tier range — professional-grade without flagship pricing.
