Antonio Bichi (1614–1691) was a Roman Catholic cardinal.
He was born in Siena to Onorata Mignanelli and Fermano Bichi. Antonio's maternal uncle was Pope Alexander VII, who named him cardinal in pectore by 1657.[1]
On 8 Dec 1652, he was consecrated bishop by Niccolò Albergati-Ludovisi, Cardinal-Priest of Santa Maria degli Angeli e dei Martiri, with Ranuccio Scotti Douglas, Bishop Emeritus of Borgo San Donnino, and Filippo Casoni (bishop), Bishop of Borgo San Donnino, serving as co-consecrators.[2]
While bishop, he was the principal consecrator of Paolo Pecci, Bishop of Massa Marittima (1679).[3]
