Renato Morelli (Campobasso, 17 July 1905 – Rome, 10 March 1977) was an anti-fascist, Liberal Italian lawyer and politician who served as Undersecretary to the Presidency of the Council of Ministers of the Kingdom of Italy in the Badoglio II Cabinet and Undersecretary of State for Foreign Affairs as well as Minister for Africa (Colonies) in the Bonomi (I and II), Parri and De Gasperi (I) cabinets.

Between 1948 and 1967 he chaired INAIL, the national workers' insurance agency and its hospital network as well as ISSA, the ILO-based International Social Security Association Born in Campobasso in 1905, he moved to Naples at a young age and, after graduating in law - as the top graduate in his year - and social sciences, he worked as a successful lawyer and collaborated for many years with Il Mattino and other Liberal newspapers, resigning his position due to his opposition to Fascism in 1939.

Under Renato Morelli's almost two decades of leadership, ISSA expanded its membership to over one hundred nations and became the prime forum for cooperation by the world's foremost social insurance organisations and agencies.
