The 2025–26 TFF Second League was the 25th season of the third-tier football league system in Turkey since its reorganization in 2001. Organized by the Turkish Football Federation (TFF), the season began on 30 August 2025 and concluded with the play-off finals on 10 May 2026.

The league continues to operate under the sponsorship name Nesine 2. Lig following a naming rights agreement established in 2024. For this campaign, the league consists of 37 clubs divided into two groups: the White Group (Beyaz Grup) with 19 teams and the Red Group (Kırmızı Grup) with 18 teams.

The winners of each group earn automatic promotion to the TFF First League, while teams finishing second through sixth in each group qualify for a promotion play-off series. Following the TFF's restructuring initiative to reduce the number of professional teams across the leagues, three teams from each group will be relegated to the TFF Third League at the end of the regular season.
