Gerakini or Yerakini (Greek: Γερακινή Greek pronunciation: [ʝeɾaciˈni], locally [ʝiracˈɲi]) is a village on the Chalkidiki peninsula in Central Macedonia, Northern Greece. It was an official settlement within the municipality of Polygyros until it was abolished in 2001.

It has been the port of nearby Polygyros, the capital of Chalkidiki, ever since its settlement. It has the largest magnesite deposits in Northern Greece.

The word Γερακινή (Yerakini) comes from γερακίνα (yerakina ([jeɾaˈcina]), meaning female peregrine falcon (falcon-gentle) (from γεράκι ([jeˈɾaci]), from ιέραξ ([iˈeɾaks]) falcon). There is a legend that the name came from a queen named Yerakina (Gerakina) who once lived in Yerakini.

In the late 1800s and early 1900s, Yerakini and nearby Kalyves Polygyrou were settled by farmers from Polygyros. The villages themselves are Greek municipalities.

Until the 1960s, there was one olive oil mill in the area, on the central beach owned by the Haji Osman family. During World War II the occupying German army, among other activities, extended the main dock, to accommodate freight vessels for their use. Divers and amateur fishers used both parts of the dock for diving and fishing. There was also a lighthouse on the right side of the main dock.

The village of Yerakini has the church of patron saints Agioi Theodoroi (dedicated to two saints having the same name Theodoros).

The annual feast-day commemorating the saints is held on the first Saturday of Lent, the religious church service being officiated by Metropolitan Nicodemus of Kassandra, the people celebrating with a number of seaside activities.

All land (fields, plains, and slopes as well as the greater part of the Trikorfo (three peaks) mountain in the east, 3.5 km from Yerakini) is covered with olive groves. The inhabitants are farmers principally growing olives for the table and their oil.
