Arcam is a British hi-fi manufacturer based in Cambridgeshire, England. The company was founded in 1976 by John Dawson and Chris Evans, science and engineering students at the University of Cambridge, under the name A&R Cambridge Ltd — short for Amplification & Recording, Cambridge. The ARCAM name began appearing on products in the 1980s and eventually became the brand's primary identity, though the legal trading name remained A&R Cambridge. In 2017 the company was acquired by Harman International, a subsidiary of Samsung Electronics, with engineering and product design continuing to be run from the UK.

Arcam's first product, the A60 integrated amplifier, became a long-running classic and helped establish the brand's reputation for understated industrial design and clean stereo performance. Over the following decades the catalogue expanded across integrated amplifiers, CD players, tuners, AV receivers and processors, and streaming components. Notable product lines include the Alpha and Delta separates of the 1980s and 1990s, the DiVA range, the FMJ (Full Metal Jacket) hi-fi and home cinema series, the Solo all-in-one music systems, and the rSeries lifestyle streamers and DACs such as the rBlink and irDAC. The brand was also an early mover in broadcast-audio hi-fi, releasing the Delta 150 NICAM tuner in 1990 and one of the first consumer DAB tuners in 1999.

Arcam operates in the home audio and home cinema space rather than the pro-audio or musical-instrument market, and its products are typically found in two-channel listening systems and dedicated home theatre installations. The company is known within audiophile circles for its Class G amplifier topology used in several of its higher-end integrated amplifiers and AV receivers, and for a house sound often described as warm and musically balanced.

Arcam has 13 products cataloged on Equipboard, including Home Amplifiers, Home Theater Receivers, and Music Streamers.
