The Nikaia Municipal Gymnasium (Greek: Δημοτικό Γυμναστήριο Νίκαιας) is a football stadium in the Athens suburb of Nikaia. It is the main playing field for the local FC Proodeftiki Korydallou playing team, and is colloquially known by the name "Proodeftiki Stadium". It is located 2 km east of the Neapolis Municipal Gymnasium, home of the Proodeftiki's local rival Ionikos FC.
The stadium is rectangular and has three stands. Regarded as one of the worse-quality football fields in Athens, it is still known as the "Cage of Korydallos" despite an overhaul in 200 that replaced the seats and added lighting.
