Evdilos (Greek: Εύδηλος) is a village and a former municipality in the central part of the island of Ikaria, North Aegean, Greece. Since the 2011 local government reform it is part of the municipality Ikaria, of which it is a municipal unit. 40 km northwest of Agios Kirykos. Its name means visible and freely rendered open horizon.

It is a new seaside settlement built after 1830 when piracy was completely stamped out on the island. Evdilos was the first capital of the island. Today it is the second port and the center of northern, central, and western Ikaria. Together with other settlements, it forms the municipal unit of Evdilos and had 2,996 permanent inhabitants at the 2021 census. The municipal unit has a land area of 78.790 km², and is the second-largest of the three on Icaria both in population and land area. It shares the island of Icaria with the municipal units of Agios Kirykos and Raches.

The picturesque small port and the pier with the old mansions and narrow roads, the paved steps, and the traditional and modern houses form an architecturally interesting village. Evdilos may be the most architecturally traditional settlement on Ikaria. There is a fine beach located just outside Evdilos.

The community of Frantato (Τοπική Κοινότητα Φραντάτου) with 728 inhabitants (2021) and 17.48 km² area lies west of Evdilos and borders neighboring Raches.
