Agios Ioannis is a village of Lasithi prefecture, in the municipality of Ierapetra, Crete, Greece.

The majority of the people that lived here have moved during the last three decades to the beach settlements of Koutsounari and Ferma, or to Ierapetra.

The water from the springs follows a route across "Milonas gorge" and ends in the sea some 7 kilometers further.

In the Aghios Ioannis area there are also a number of beaches, including the Long beach and Aghia Fotia.

The community of Agios Ioannis is represented by a five-member council headed by the Emmanouil Kidonakis.
