Ramón Llenas was a Spanish voice actor and musician known for his contributions to dubbing and character interpretation in Catalan and Spanish. His career in voice work was part of a broader artistic life that included significant periods as a guitarist and singer.

Llenas was active in dubbing from at least the late 1990s. One of his earliest documented credits in animation is from 1999, where he participated as a chorus singer in the Catalan-language dubbing of the Disney film Dumbo. His voice can be heard in several of the film's musical numbers, including Casey Junior, Song of the Roustabouts, Hit the Big Boss, Pink Elephants on Parade, and When I See an Elephant Fly.

In the realm of anime and animated series, Llenas is recognized for his role as the voice of Vell Guardià in the Catalan dub of Maeterlinck's Blue Bird. He also contributed his voice to other iconic animated series of the era. He performed the theme song for the Catalan version of The Smurfs (Els Barrufets) and provided the voice for the character Decta-cubitus in the classic anime series Musculman (known as Kinnikuman in other regions). His work extended to film dubbing as well; he was part of the Spanish voice cast for the 2001 DreamWorks animated feature Shrek, where he sang in the choir.

Beyond animation, Llenas's career as a vocalist encompassed singing and adapting songs for television commercials, including spots for brands like Eau Jeane and Chispas. This versatility as a performer was a hallmark of his professional life. Prior to his extensive voice work, which became more prominent from the 1980s onward, Llenas had a notable career as a musician. He was a guitarist and singer who played with various bands, including Rudy Ventura's ensemble, and recorded under the stage name Ray L. Falcon.
