Telekom Malaysia Berhad (MYX: 4863), DBA TM, is the largest integrated solutions^{[clarification needed]} provider in Malaysia, and one of Asia's leading communications companies, with a market capitalisation of RM13.9 billion and a workforce of 26,629 employees. Established as the Telecommunications Department of Malaya in 1946, it was privatised in 1987, and listed on Bursa Malaysia in 1990. Subsequent growth led to a demerger in 2008 of TM's mobile and fixed services, allowing the company to focus more intently on its core businesses of Internet and multimedia, data and fixed-line services.

TM's history goes back to the establishment of the Telecommunications Department of Malaya in 1946. In 1962 the company introduced Subscriber Trunk Dialling (STD) between Kuala Lumpur and Singapore via the first long-distance microwave link. The following year, the company expanded its microwave network throughout the country.

In 1968, the Telecommunications Department of Malaya was merged with the Telecommunications Department of Sabah and Sarawak to form the Telecommunications Department of Malaysia, also known by its Bahasa Malaysia name, Jabatan Telekom Malaysia (JTM). The company would work under this name for almost two decades. Significant milestones during this period include:
