Saint Peter's Battery (Maltese: Batterija ta' San Pietru) was an artillery battery in Kalkara, Malta, built by Maltese insurgents during the French blockade of 1798–1800.

It was part of a chain of batteries, redoubts and entrenchments encircling the French positions in Marsamxett and the Grand Harbour.

It possibly had a vaulted underground chamber which served as a barracks.

Like the other French blockade fortifications, St. Peter's Battery was dismantled, possibly sometime after 1814.
