Naim Audio is a British high-end hi-fi manufacturer founded in 1973 by Julian Vereker and based in Salisbury, Wiltshire, England. The company built its reputation on the idea that amplifiers shape a system's sound as much as the loudspeakers, an argument pressed home by the NAP250 power amplifier and the long-running NAIT integrated amplifier. Naim designs are recognizable for their heavy toroidal transformers, careful earthing and screening, and a preference for DIN and BNC connectors over standard RCA, paired with matched-component systems intended to be built up as stacks of separates.

The product range covers traditional separates (preamps, power amps, CD players such as the CDS series, and phono stages) alongside network streamers and all-in-one solutions. The Uniti range of streaming players, introduced in 2009, and the Mu-so wireless speaker family, introduced in 2014, brought Naim into the digital and lifestyle audio market, and the New Classic Series arrived in 2023 as a modern update to the company's core separates. Naim has also supplied OEM audio systems to Bentley Motors.

Following a 2011 merger with French loudspeaker manufacturer Focal, Naim operates under the Vervent Audio Group, and the two brands are sold together through the Focal Powered by Naim dealer network. The company also runs Naim Records, a jazz-leaning label founded in 1993 whose catalogue includes releases from artists such as Charlie Haden, Kurt Elling, Sons of Kemet, and Yazz Ahmed.

Naim has 7 products cataloged on Equipboard, including Music Streamers, Home Amplifiers, and Smart Speakers.
