T-shirt bearing illustration of Nagra sound equipment, 1970.

Nagra is a brand of portable audio recorders produced from 1951 in Switzerland.

The machines were initially designed by Polish inventor Stefan Kudelski and his company won numerous technical awards for their precision and reliability. Nagra means "[it] will record" in Polish.

Nagra-brand tape recorders were widely used for sound recording systems for motion picture and (non-video) single-camera television production from the 1960s until the 1990s.
