Each den is led by an adult den leader in addition to other parents, together they plan and carry out a year-round program of activities for the den. Many parents serve as a Den Leader or Assistant Den Leader.

Kindergarten – Lion and  first-grade – Tiger dens use a shared-leadership model, which means that the den leader works with a different Lion/Tiger adult partner each month to plan the den’s program. This team hosts that month’s den meetings as well as the den’s part in the pack meeting.

In second-grade Wolf, third-grade Bear, and fourth/fifth grade Webelos Scout dens, the den leader works with an assistant den leader or co-leader and potentially, a den chief (an older Scout from a troop, crew, or ship). The den may also elect a denner and an assistant denner, who are Cub Scouts in the den, to work with the den leader and den chief.
