Barcus-Berry is an American manufacturer of pickups and transducer systems for acoustic and orchestral instruments, founded in 1964 by audio engineer Les Barcus and violinist John Berry. Growing out of experiments the two began in 1963, the company is credited with developing the first commercial piezo crystal transducer pickup for musical instruments, a technology that shaped how string, wind, piano, and percussion instruments are amplified.

The brand's catalog centers on piezo pickups and preamps for violin, viola, cello, and upright bass, alongside acoustic guitar transducers and piano/harp systems. Representative products include the 3100 and 3110 clamp-on violin bridge piezo pickups, the 1320 violin bridge with built-in pickup, the 1457 acoustic guitar transducer, the 3000A Piezo Buffer Preamp with EQ, and the 4000 Planar Wave piano and harp pickup system. Barcus-Berry also produces acoustic-electric violins such as the Vibrato AE, offered in the signature Barcus-Berry Blue finish.

In 1985 the company was acquired by a group of investors led by former Yamaha and CBS executive John McLaren, and the Barcus-Berry pickup and transducer business became part of what is now BBE Sound, based in Huntington Beach, California. Players associated with the brand's violins and pickups include Jean-Luc Ponty, Doug Kershaw, and Charlie Daniels.
