Astakos (Greek: Αστακός, meaning "lobster") is a town and a former municipality in Aetolia-Acarnania, West Greece, Greece. Since the 2011 local government reform it is part of the municipality Xiromero, of which it is a municipal unit. The municipal unit has an area of 345.099 km2. It is located on a bay on the eastern shore of the Ionian Sea, near the southern end of the Acarnanian Mountains. It takes its name from the ancient Acarnanian town Astacus (Ancient Greek: Ἄστακος - Astakos), and was named Dragamesti in the Middle Ages. It is speculated to be the site of ancient Dulichium.
The municipal unit Astakos is subdivided into the following communities (constituent villages in brackets):
- Astakos (Astakos, Valti)
- Strongylovouni (Strongylovouni, Manina Vlizianon)
The city has a port able to hold ferries. The countryside mainly produces wheat, corn and few grapes. Fishing is an important source of income.

- Astakos is also the birthplace of the fictional characters Xeones, Diomache, and Bruxieus in Steven Pressfield's novel Gates of Fire. Cousins Xeones and Diomache, and Bruxieus, their tutor, all survive the sack of Astakos by Argos (cir. 500 BC); Xeones later becomes a perioikoi of Sparta and serves at the Battle of Thermopylae as a squire to the Spartiate Dienekes.
