The 3. Liga is the third-tier football league in Slovakia, established in 1993. As of the 2024–25 season, it comprises 33 teams divided into two geographical groups: 3. liga Západ (West) and 3. liga Východ (East). The league operates under the jurisdiction of the Slovak Football Association and serves as a feeder league to the 2. Liga, with top-performing teams earning promotion. Conversely, teams finishing at the bottom face relegation to the 4. Liga. The league also provides teams the opportunity to compete in the national Slovak Cup.
