Adamo Rossi (March 5, 1821 in Petrignano – February 22, 1891 in Perugia) was an Italian clergyman, revolutionary patriot, scholar and librarian.
Back in Perugia, he maintained a long correspondence with the government of the Roman Republic, which at the time seized power in the city of Rome and expelled the Pope.
This caused Rossi to be suspended from his clerical position by Pope Pius IX and removed from his teaching job.
He devoted himself entirely to the study of palaeography, diplomatics and the social, literary and artistic history of Perugia, and produced extensive publications.
He underwent a lengthy administrative and judicial investigation, which eventually exonerated him of the theft but did reveal evidence of gross negligence.
