Dimotiko Theatro (Greek: Δημοτικό Θέατρο, lit. 'Municipal Theatre') is a station in Piraeus, Greece. It is the southwestern terminus of Athens Metro Line 3. It opened in October 10, 2022, as part of the Line 3 extension to Piraeus.

The station was first planned along with the rest of the Haidari-Piraeus extension in 2000 and was planned to be located between Piraeus and Evangelistria. In February 2009, construction of Evangelistria station was cancelled, thus making Dimotiko Theatro the planned terminus of the extension. Construction started in 2012 and was due to be completed in 2017 but was pushed back to 2022, mainly due to problems regarding the construction of Piraeus station. The TBM arrived at Dimotiko Theatro in November 28, 2017.

The station has three entrances. One at Venizelou Square, one at Korai Square and one at Pavlou Bakoyianni Square. The entrances at Venizelou and Korai Square are ADA accessible.

The tram stop that connects with Dimotiko Theatro is called Dimarcheio (Greek: Δημαρχείο), after the nearby town hall of the Piraeus Municipality. It is located between the two halves of Korai Square.

Dimarcheio opened on 15 December 2021, as part of the extension of the Athens Tram to Piraeus. Dimarcheio is part of the Piraeus loop, and serves westbound Line 7 trams towards Agia Triada.
