Fabrizio Verospi (1571 - 27 January 1639) was an Italian Catholic Cardinal and a curial judicial official.
Verospi was born in 1571 in Rome, the son of Girolamo Verospi and his wife Penelope Gabrielli and the uncle of Girolamo Verospi who was later also elevated to Cardinal.
He studied law in Rome and Perugia and then at the University of Bologna where he earned a doctorate in utroque iure. He was subsequently employed as a domestic prelate, auditor of Fermo and, in 1595, referendary of the Tribunals of the Apostolic Signature of Justice and of Grace. In 1597 he was appointed governor of Cesena and then of Fermo.
In 1611 Verospi became a cleric of the Apostolic Chamber and auditor of the Sacred Roman Rota. The latter role he held for 16 years and gained a reputation for expert legal opinion, detailed and lengthy judgements and an adherence to precedent.
In 1619 he was appointed nuncio extraordinary to Vienna and soon after was responsible for the arrest of Cardinal Melchior Klesl who had refused to act against Protestants after the Bohemian Revolt. He was again named nuncio extraordinary to Vienna in 1622 to act as a witness to the marriage of Emperor Ferdinand II and Princess Eleonora Gonzaga. At the same time, he oversaw the transfer of Cardinal Klesl to Rome.
