Pserimos (Greek: Ψέριμος Δωδεκανήσου) is a small Greek island in the Dodecanese chain, lying between Kalymnos and Kos in front of the coast of Turkey. It is part of the municipality of Kálymnos, and reported a population of 130 inhabitants at the 2001 census.
The main industry is tourism, with Greek and other European holidaymakers attracted by its remote location. There are several beaches and a number of taverns, some of which offer accommodation.
Pserimos is served by a daily ferry from Pothia, on the island of Kalymnos, and is a destination on the itinerary of a number of cruise boats in the area.
