Filfla is a mostly barren, uninhabited islet 4.5 kilometres (2.8 miles) south of Malta, and is the most southerly point of the Maltese Archipelago.

Filflu (or Filfluu), a rocky islet some 101 metres (331 feet) southwest of Filfla,[1] has the southernmost point of Malta.

The island has been identified as an Important Bird Area (IBA) by BirdLife International, principally because of the storm petrel colony.

Access to Filfla is only possible for educational or scientific purposes, subject to prior permission from the Environment and Resources Authority.

The Filfla Natural Reserve Act, enacted in 1988, provided for further restrictions on access and use, including a prohibition on fishing within one nautical mile (1.9 km) around the island due to the possibility of encountering unexploded ordnance.
