The J18 Region, formerly called J18 Elit until 2020, is the highest level of under-18 ice hockey in Sweden.
At Christmas, the five best teams from each division qualify for the J18 Nationell to determine the Swedish U18 Championship.
The league is divided into four divisions, Norra (North), Södra (South), Västra (West), and Östra (East).
The five best teams from each division qualify for the Winter series known as J18 Allsvenskan, divided into Norra and Södra, while the remaining teams have to play in a continuation series during Winter for their specific division.
These "Winter" series are played between January and March of the following year.
