Falkonera

thumb|Falkonera in 2012 Falkonera () or Gerakoulia (Γερακούλια), anciently known as Hierakia (Ἱεράκια), is a small uninhabited Greek island in the southwestern Aegean Sea, between the island of Milos and the Peloponnese region. Although outside the Saronic Gulf, it is generally included among the Saronic Islands. The islet marks the summit of a horst tending WNW-ESE, which separates the Myrtoon basin to the north from the Cretan basin to the south.

The island is administered as part of the Islands regional unit, part of the municipality of Spetses. Located at the crossing of the Piraeus–Chania and Cape Maleas–İzmir shipping lanes, it is considered a significant navigational hazard due to the strong surrounding currents. At the island's eastern cape, named Panaghia ton revmaton (Παναγιά των Ρευμάτων), meaning "Panagia of the currents", there is a lighthouse that was destroyed by the Germans in 1941 and rebuilt after World War II. The highest point of the island is 183 meters above sea level.
