The TFF Second League, also known as the TFF 2. Lig, is the third tier of professional football in Turkey. It operates under the governance of the Turkish Football Federation (TFF) and serves as a crucial step for clubs aiming to reach the higher divisions, specifically the Süper Lig and the TFF First League. The league consists of multiple teams that compete in a round-robin format, with each team playing home and away matches. The top teams at the end of the season can earn promotion to the TFF First League, while the lower-performing teams face the risk of relegation to the TFF Third League.
