Giulio Serafini, J.U.D. (12 October 1867 – 16 July 1938) was a Cardinal of the Roman Catholic Church who served as President of the Pontifical Commission for the Authentic Interpretation of Code of Canon Law and Prefect of the Congregation of the Council.
Serafini was born in Bolsena, Italy. He was educated at the Minor Seminary of Orvieto and the Roman-Pio Seminary, Rome, where he earned a doctorate utriusque iuris (in both canon and civil law). He was ordained a priest on 6 April 1890. He served as a faculty member of the Seminary of Orvieto from 1895 until 1901 and was its rector from 1897 until 1901. He was created Privy chamberlain of His Holiness on 7 January 1904.
Pope Pius X appointed him Bishop of Pescia on 4 March 1907, and he was consecrated on 26 May by Pietro Respighi, Cardinal Vicar of Rome. On 21 December of the same year he was transferred to the titular see of Lampsacus.
Pope Pius XI created and proclaimed him Cardinal-Deacon of Santa Maria sopra Minerva in the consistory of 30 June 1930, and named him President of the Pontifical Commission for the Authentic Interpretation of Code of Canon Law, an appointment to which he added on 4 July 1930 that of Prefect of the Congregation of the Council.
Serafini held both positions until his death in 1938. He is buried in the church of Santa Maria sopra Minerva in Rome.
