Sant Agostino alla Zecca, also known as Sant'Agostino Maggiore is a church in central Naples, Italy.

Originally granted to the Augustinian monks by Robert I of Anjou in 1259.

The church underwent extensive reconstruction in the Baroque period by Bartolomeo Picchiati.

Since the 1980 Irpinia earthquake, it has been closed and is in a poor state of conservation.

The interior has frescoes of Giacinto Diano in the Sacristy.
