Avlaki (Greek: Αυλάκι) is a village in the regional unit of Phthiotis, Central Greece.

Avlaki lies some 13 kilometres (8.1 mi) east of Lamia, near the northern coast of the Malian Gulf.

[2] Avlaki is first mentioned (Aulachi) in 1423, when it and Stylida were transferred to the Republic of Venice by the Byzantine governor of Lamia, in order to protect them from being captured by the Ottoman Empire.

[2] A medieval fort, known locally as Palaiopyrgos, using ancient spolia, was located on the shore.

[2] Another nearby hill shows traces of fortifications, theorized to be either medieval Ravennika or the ancient city of Phalara.
