라브리오

In 1990, Lavrio was established. From 1990 to 2002, the club competed in the neighborhood regional ESKA leagues. The club then spent five years playing at the Greek C National League level, from 2002 until 2007, when the club was promoted to the Greek B National League. During the club's first two seasons in the Greek National B League, 2007–08 and 2008–09, Lavrio ranked 6th in the final league standings. But the next season, 2009–10, it was declared the champion team of the category, after winning a tie-breaker with Panelefsiniakos (24 wins and 6 losses ). Therefore, for the first time in the club's history, it came up to the Greek A2 National League. At the same time, in the Greek Cup competition, the club was eliminated after four games, losing in the 2nd leg of the second phase of the tournament, against PAOK, by a score of 73–83.

During its first season in the Greek A2 Basket League, in 2010–11, Lavrio finished in 4th place in the league standings. In the Greek Cup tournament, the club was eliminated on the 2nd game day, where they were defeated by a score of 69–63, against Nea Kifissia. In the following season, 2011–12, while still competing in the Greek A2 League category, they finished in 8th place in the league standings. In the course of the Greek Cup, they were eliminated on the 2nd game day of Phase A, after being defeated by a score of 74–59, against Panerythraikos. In the 2012–13 season, the team continued its good performances, and finished in 5th place in the final standings of the league classification tables. In the Greek Cup, they were eliminated at the first game of the second phase, when they were defeated by Ikaroi Serron, by a score of 64–60.

In the 2014–15 Greek A2 Basket League season, Lavrio finished in third place in the league. Because the club KAOD withdrew from the top-tier level Greek Basket League, Lavrio was then promoted up to the top professional national basketball league in Greece, for the first time in its history. Lavrio managed to secure their place in the league for the next season, one game before the end of the season, even though the team lost that game to Aries Trikala. The club finished the 2015–16 Greek League season in 11th place.

The club played in a European-wide competition for the first time in the 2018–19 season, as it competed in the first qualifying round of Europe's fourth-tier level competition, the FIBA Europe Cup. On September 20, 2018, Lavrio played its first European game, which resulted in an 82–73 victory over the Ukrainian SuperLeague club Dnipro. Lavrio made it to the finals of the 2020–21 Greek Basket League season, and thus qualified to play in the European-wide secondary competition, the FIBA Champions League, in the 2021–22 season.
