is a Greek professional basketball club that is located in Kymi, on the island of Euboea, Greece.

Kymis was also one of the original 28 founding clubs of the Hellenic Amateur Athletic Association (SEGAS) in 1897.

In May 2012, the club named Vassilis Bratsiakos, as the men's team's head basketball coach.

The rise of the club's status in the 1st ESKASE local regional league continued the following year, when Kymi won their local regional championship against A.C. Kymi, and gained promotion to the Greek lower level national leagues.

With Vassilis Bratsiakos as the head coach, Kymi became the champion of the 4th-tier level Greek C Basket League, finishing with 19 wins and just one defeat.

Continuing its upward trend, the club once again finished in the top of the final standings, having collected 24 wins and 2 losses, against 13 rivals, while maintaining an unbeaten record at home games.

During the 2015 summer transfer window, Kymi managed to make some very good transfers (for that level of competition), including Stavros Toutziarakis, Ioannis Psathas, Alexandros Sigkounas, and Vaidas Kariniauskas, who was signed from the EuroLeague team Žalgiris Kaunas.

The club normally plays its home games at the Nikos Marinos Indoor Hall, a small arena that originally had a capacity of about 500.

While the Nikos Marinos Indoor Hall was being renovated, Kymi decided to play their home Greek Basket League games at the 1,620 capacity Tasos Kampouris Kanithou Indoor Hall,[4] which is also located on the island of Euboea, in Chalcis.
