Muljadi Djojomartono (EYD: Mulyadi Joyomartono; 3 May 1898 – 23 October 1967) was an Indonesian politician and military officer who served as Coordinating Minister for People's Welfare between 1960–1966 and Minister of Social Affairs between 1957 and 1962 and briefly in 1966. Affiliated with the Islamic organization Muhammadiyah, he had originated in Surakarta and served as a battalion commander in the Defenders of the Homeland organization, which resulted in his participation during the Indonesian National Revolution as an officer in his hometown. He was appointed as a minister by Sukarno despite protestations from his political party and Muhammadiyah, which opposed Muljadi's accommodation of Sukarno's actions.
