Sant'Eustachio is a Roman Catholic titular church and minor basilica in Rome, named for the martyr Saint Eustace. It is located on Via di Sant'Eustachio in the rione Sant'Eustachio, a block west of the Pantheon and via della Rotonda, and a block east of Sant'Ivo alla Sapienza and the Via della Dogana Vecchia.
The church was founded in the 8th century, or possibly even earlier . The church was recorded as a diaconia (a centre for helping the poor and the sick) at the end of the pontificate of Pope Gregory II (715-731). It is mentioned in some documents dating from the 10th and 11th centuries, where this church is called in platana (between the plane trees) referring to the tree planted in the garden of the martyr Eustace. The emperor Constantine I had previously built an oratory on this same spot. This church was called "ad Pantheon in regione nona e iuxta templum Agrippae" (at the Pantheon in the ninth region and next to the temple of Agrippa").
The church was restored (including the addition of a new campanile). at the end of the 12th century during the pontificate of Pope Celestine III (1191–1198), who also deposited the relics of the martyr in the church. In the 16th century, it was a favoured praying-place for St Philip Neri. In the 17th and 18th centuries it was almost completely rebuilt (with only the campanile remaining from the old structure). The church was designed in the Roman Baroque style. The work was done by several architects : Cesare Corvara and Giovanni Battista Contini (1641–1723), who added chapels and the portico, Antonio Canevari (1681–1750), Nicola Salvi (1697–1751) and finally, from 1728, Giovanni Domenico Navone. The new high altar, in bronze and polychrome marble, was added by Nicola Salvi in 1739 and in 1749 Ferdinando Fuga put a baldachin over it. The choir and the sacristy were designed by Canevari and built by Giovanni Moscati.
