Torremaggiore is a town, comune (municipality) and former seat of a bishopric, in the province of Foggia in the Apulia (in Italian: Puglia), region of southeast Italy.

It lies on a hill, 169 metres (554 ft) over the sea, and is famous for production of wine and olives.

The history of Torremaggiore is strictly connected to that of the burg of (Castel) Fiorentino (di Puglia), a Byzantine frontier stronghold founded by the Italian catepan Basil Boioannes in 1018.

In 1391 it was suppressed and its territory merged into the Diocese of Lucera.

The name Fiorentino (Florentinensis) has been used, since 1969 as a Latin Catholic titular bishopric.
