The Optimist Junior Interclub Curling League is a league of curlers that play each week.

The league consists of teams from various curling clubs throughout the lower mainland of British Columbia.

The clubs that have participated in the program extend from the Chilliwack Curling Club to the Squamish and Gibsons Curling Clubs. Teams from the Seattle Granite Club in Washington State are also part of the league.

Curlers that compete in the league also belong to a junior curling program at their home club.
