Kritsa (Greek: Κριτσά, romanized: Critsá) is one of the oldest and most picturesque villages in Crete, Greece, built amphitheatrically on a rock hill, named Kastellos, surrounded by olive groves, at an altitude of 375 m. It is part of the municipality of Agios Nikolaos.

It is located 10 km from Agios Nikolaos and has about 2200 inhabitants who live in different neighborhoods named Palemilos, Koukistres, Christos and Pergiolikia.

[citation needed] Near the village, three kilometers to the north, are the ruins of the ancient Greek city Lato, which was noted as one of the most powerful Dorian towns in Crete, with two acropoleis.

The oldest settlement in the Kritsa area, on the steep rocky hill south of the village named Kastellos, dates back to the 13–12th centuries BCE (Late Minoan IIIC).

From Kritsa there is an interesting and spectacular climb to the plateau of Katharo, which provides a panoramic view of Mirabello Bay, Agios Nikolaos and Kalo Horio.
