Ottavio De Liva (10 June 1911 – 23 August 1965) was an Italian prelate of the Catholic Church who worked in the diplomatic service of the Holy See.
Ottavio De Liva was born on 10 June 1911 in the town of Sevegliano, Bagnaria Arsa, Province of Udine, Italy, the sixth of seven children.
[3] In 1950, during a period of intense conflict between the Church and the government of Czechoslovakia, De Liva, though only the secretary, was the last Vatican diplomat remaining in the nunciature.
He therefore acted on behalf of the nunciature there for eight months as the government delayed approving a visa to allow the newly appointed chargé d’affaires to enter the country.
On 16 March, the government ordered him to leave the country within three days; it accused him of "subversive, anti-state activity", staging phony miracles, interfering in internal affairs, and "misusing his official position".
