Agioi Theodoroi (Greek: Άγιοι Θεόδωροι) are two uninhabited islets off the coast of western Crete.

[2][3][4] The islands are mentioned in antiquity (2nd half of the third century) in the Stadiasmus Maris Magni, which states that they have potable water.

[5] The islets have been recognised as an Important Bird Area (IBA) by BirdLife International because they support a breeding population of 50 – 65 pairs of Eleonora's falcons.

[6] In 1930 the municipality of Agia Marina with the cooperation of the hunting association of Chania decided to make the islands a nature reserve.

It was in 1935 that Theodoros Viglis caught one male and two female kri-kri, or Cretan goats, in Samariá Gorge and released them on Agios Theodoros so that they could breed with integrity since no other goats inhabited the island.
