Daulis was an ancient greek city in Phocis.

According to greek mythology Daulis had been the home town of Tereus. The city is mentioned by Homer. It is said to be named after a nymph Daulis, a daughter of the river-god Cephissus.

During the Greco-Persian Wars Daulis had been destroyed for the first time in 480 BC. In 395 BC the city was attacked by Thebes. In 346 BC Daulis was destroyed again during the so called Third Holy War. In 220 BC the city was attacked by the Aetolians. In 198 BC the Romans occcupied Daulis by a stratagem.

In Late Antiquity, Daulis was a seat of a bishop.

Remains of the city walls can be seen today near the modern town Davlia.

Homer , Iliad Book 2

Schedius and Epistrophus, sons of Iphitus,
the son of great-hearted Naubolus,                                               
commanded Phoceans—men from Cyparissus,                          
rocky Pytho, holy Crisa, Daulis, and Panopeus;  
men from Anemorea and Hyampolis;
from around the sacred river Cephissus,  
from Lilaea, beside Cephissus' springs.
Forty black ships these two leaders brought with them. 
Moving around, as soldiers armed themselves, 
they set Phocean ranks by the Boeotians, on their left.

In Late Antiquity Daulis had been a seat of a bishop.

Remainings of the city walls can be seen today near the modern town Davlia.
