Agia Eirini (Αγία Ειρήνη) is a small community in Western Crete, population 58 (2021 census).

It is in the municipality of Kantanos-Selino, which forms the southwest part of the region, specifically the East Selino unit, and the community of Epanochori.

The importance of Agia Eirini lies in that constitutes the north end of the gorge that takes its name from this village.

The gorge is popular with trekkers, bringing tourists north from the beach resort of Sougia where it ends.

[2] The village lies on the road from Chania to Sougia, 40 km south of Chania at an altitude of 650m, located at the foot of Apopigadi, south of Prases (in neighbouring Mousouroi, Platanias) on the north side of the pass, just past where the road branches east to Omalos at the wind turbine line on the ridge, and just north of Epanochori itself.
