Aircraft Radio Corporation (ARC) – not to be confused with Aeronautical Radio, Inc. (ARINC) – was a principal pioneer and major manufacturer of avionics for military and commercial aircraft, and later general aviation (light) aircraft, from the 1920s to the 1950s—subsequently acquired and rebranded by a succession of other companies, each of whom changed the official name, of the enterprise, while initially continuing ARC's primary function, staffing, facilities and product focus.

Consequently, many in the aviation industry—including many within its current and former parent companies—have unofficially referred to ARC, by its original name, as a continuing specific entity, regardless of its official names or owners at any point in time.
