Youth rugby in Illinois is organized as local clubs fielding teams in one or more divisions (by age/grade and gender). Most clubs draw players from many schools in an area, although many clubs recruit exclusively or largely from one school. There are also a growing number of school-based clubs and school-sponsored varsity teams.

The largest concentration of clubs are in the Chicago Suburban area, with a growing presence in the city of Chicago, Central Illinois, Northern Illinois, and Southern Illinois.
