Mustaches for Kids is an annual Mustache-growing fundraiser that is held in cities throughout the United States and Canada.Each year, participants ("Growers") raise money by growing sweet, sweet mustaches between Thanksgiving and Christmas. They shave their faces, except for the Mustache, a minimum of one time per week. The Growers solicit donations from friends, family, co-workers, and people in the community.

At the end of the Growing Season, Mustaches for Kids hosts a party, called The Stache Bash, where the facial hair is evaluated by an independent panel of judges, and one Mustache is declared to be the "Sweetest." Other Growers are recognized for growing the Worst Mustache and for raising the most money.

Over the past eight years, Mustaches for Kids has spread across the world, a steady expansion that is not unlike the measured, deliberate growth of a Mustache. Mustaches for Kids has enjoyed the efforts of an impressive number of Growers who, collectively, have raised over $150,000 for the Make-A-Wish Foundation, and other children's charities.

In this, the fourth year, the Nashville chapter will again be raising money for The Michael Stanley Child Life Fund, for Monroe Carell Jr. Children’s Hospital at Vanderbilt, a 501(c)(3) non-profit organization. This fund is dedicated to supporting families of children with cancer.
