The 2025–26 season was FC Thun's first season in the top flight of Swiss football since their promotion in the 2024–25 season.
Thun would perform a historic feat by leading the table ahead of the winter break in December, thus being crowned "winter champions".
On 3 May 2026, Thun secured the Swiss Super League title for the first time in their history after second-placed St. Gallen lost 3–0 at home to Sion with three matches remaining.
