Albert Manoempak Sipahoetar (26 August 1914 – 5 January 1948), often credited as A. M. Sipahoetar, was an Indonesian journalist and one of the founders of the state news agency Antara. Born in Tarutung, Dutch East Indies, he took up journalism at an early age and by age 20 had led two publications. After a time working in Medan, he went to the capital at Batavia (now Jakarta) with Adam Malik. After dabbling in politics and advertising, he established Antara together with three other reporters, heading the agency for a year between 1938 and 1939. Although he remained active as a reporter after leaving the agency, his health failed quickly and he died in a sanatorium near Yogyakarta.
