IV liga Silesia group (grupa śląska), also known as I liga Śląska InterHall for sponsorship reasons,[1] is one of the groups of IV liga, the fifth level of Polish football league system.
The league was created in the 2000–01 season after introducing new administrative division of Poland.
Until the end of the 2007–08 season,[2] IV liga was the fourth tier of league system, but this was changed with the formation of the Ekstraklasa as the top level league in Poland.
From its inception, IV liga Silesia was divided into subgroups, before switching to a single group format in 2024.
The bottom teams are relegated to the groups of Liga okręgowa from Silesian Voivodeship.
