Western Electric Company (sometimes abbreviated WE and WECo) was an American electrical engineering company, the manufacturing arm of AT&T from 1881 to 1995. It was the scene of a number of technological innovations and also some seminal developments in industrial management. It also served as the purchasing agent for the member companies of the Bell System.

In 1856, George Shawk purchased an electrical engineering business in Cleveland, Ohio. In 1869, he became partners with Enos M. Barton and, later the same year, sold his share to inventor Elisha Gray. In 1872 Barton and Gray moved the business to Clinton Street, Chicago, Illinois and incorporated it as the Western Electric Manufacturing Company. They manufactured a variety of electrical products including typewriters, alarms, and lighting and had a close relationship with the telegraph company Western Union to whom they supplied relays and other equipment.

In 1875, Gray sold his interests to Western Union, including the caveat that he had filed against Alexander Graham Bell's patent application for the telephone. The ensuing legal battle over patent rights, between Western Union and the Bell Telephone Company, ended in 1879 with Western Union withdrawing from the telephone market and Bell acquiring Western Electric in 1881.
