Harem Spor

In the 2021-2022 Turkish Basketball Second League (TB2L) final, Harem Spor lost the deciding game to Fenerbahçe Koleji Safiport 82-81. A year later, in the 2022-2023 promotion final, the club drew Samsunspor and did not let the finish line slip a second time, taking the series 3-2 to reach the Turkish Basketball League (TBL) for the first time.

The rise had started lower down. Harem Spor won the Turkish Basketball Third League (TB3L) in 2020-2021, its first title, to move up to the TB2L, then won that division two years later.

Founded in 2019, the club is owned and chaired by Cem Efe, whose jewelry business, CeMeFe Gold, gave Harem Spor the tag by which it is still known, the "jewelers' team." It plays in red and white.

Its home has not stayed still either. Harem Spor spent the 2023-2024 season in Istanbul, at the 1,000-seat Beylikdüzü Spor Salonu, before a partnership with the local municipality took the club to Yalova in June 2024, where it now plays as Yalova Harem Spor at the 90. Yıl Spor Salonu, seating 2,500.

What the club has not done is win at the level it now occupies. Since reaching the TBL, Harem Spor has no top-flight championship and no Turkish Federation Cup to its name.
