Angelo Jacobini (25 April 1825 – 3 March 1886) was an Italian prelate of the Catholic Church who spent his entire career in the Roman Curia.

He then held a series of positions in the Roman Curia, beginning as auditor of the Congregation of the Council.

[3] In 1873, he gave testimony in Ireland in a lawsuit for defamation brought by a parish priest against Cardinal Paul Cullen, Archbishop of Dublin; he contributed to Cullen's successful defense of his suspension of the priest.

Pope Leo XIII made him a cardinal deacon on 27 March 1882;[5] he was assigned the deaconry of San Eustachio.

[1] To avoid confusion with his cousin Cardinal Luigi Jacobini's coat of arms, which used the Jacobini family's coat of arms, he added elements from his mother's family.
