Lion is a national pilot program of the Boy Scouts of America for kindergarten-age boys. The mission of the Boy Scouts of America is to help young people build character, learn citizenship, develop personal fitness, become effective leaders, and have fun in the outdoors. Cub Scouting is a program of the Boy Scouts of America for boys in the first through fifth grades. The Lion pilot is exploring the value of a Scouting program for kindergarten-age boys. (Boys must be 5 years old by September 30 and not yet 7 years.)

Lion is a family-oriented program. A youth and his parent or caring adult partner join Scouting together. A group of six to eight boys and their adult partners meet together in a group called a den. Dens will meet approximately twice per month. They have fun participating in den meetings and outings while making memories together.

The Lion pilot encourages boys to learn and explore through hands-on, high-energy activities. Adult partners take turns leading a den meeting or outing during the year. Most meetings last approximately 45 minutes to an hour; outings are slightly longer.
